Randy Randall Rudy Quaid (born October 1, 1950) is an American film and television actor and Academy Award nominee known for his roles in both serious drama and light comedy. He was nominated for a Golden Globe Award, BAFTA Award and an Academy Award for his role in The Last Detail in 1973. In 1978 he co-starred as a prisoner in Midnight Express. Quaid also won a Golden Globe and was nominated for an Emmy Award for his portrayal of U.S. President Lyndon Johnson in LBJ:
In 2004, Quaid appeared on stage undertaking the starring role of Frank in the world premiere of Sam Shepard's The God of Hell, produced by the New School University at the Actors Studio Drama School in New York. In The God of Hell, Quaid's portrayal of Frank, a Wisconsin dairy farmer whose home is infiltrated by a dangerous government operative who wants to take over his farm, was well-received and -reviewed by New York City's top theatre critics. It marked the second time that Quaid starred in a Shepard play, the first being the long running Broadway hit True West. In February 2008, a five-member hearing committee of Actors' Equity Association, the labor union representing American stage actors, banned Quaid for life and fined him more than $81,000. The charges that brought the sanctions originated in a Seattle production of Lone Star Love, a Western-themed adaptation of Shakespeare's The Merry Wives of Windsor, in which Quaid played the lead role of Falstaff. The musical was scheduled to come to Broadway, but producers cancelled it. According to the New York Post, all 26 members of the musical cast brought charges that Quaid "physically and verbally abused his fellow performers" and that the show closed rather than continuing to Broadway because of Quaid's "oddball behavior". Quaid's lawyer, Mark Block, said the charges were false, and that one of the complaining actors had said the action was driven by "the producers who did not want to give Randy his contractual rights to creative approval ... or financial participation ..." Block said that Quaid had left the union before the musical started, making the ban moot, and that Quaid only participated in the hearing because he wanted due process. Quaid's statement on the charges was "I am guilty of only one thing: giving a performance that elicited a response so deeply felt by the actors and producers with little experience of my creative process that they actually think I am Falstaff."

why did he participate in the hearing?

because he wanted due process.

The Houston Livestock Show and Rodeo, also called RodeoHouston or abbreviated HLSR, is the largest livestock exhibitions and rodeo in the world. It also includes one of the richest regular-season rodeo events. It has been held at NRG Stadium in Houston, Texas, since 2003. It was previously held in the Astrodome.
Since 1952, traditional trail rides have been a part of the Houston Livestock Show and Rodeo. As of 2017, there were 13 official trail rides, totaling over 3,000 riders. The trail rides range in size from a dozen to over one thousand people who ride on horseback or in horse-drawn wagons from various areas of the state to Houston. They make their way at about 3 miles (4.8 km) per hour, covering up to 17 miles (27 km) each day. Many of the routes take place in part along major highways and busy city streets, making safety a major concern. The trail rides last from a few days to three weeks, depending on the distance they cover. Some of the participants are able to join only on weekends or at the end of the trip. The days start very early, and often end with live music or a small celebration. Many riders choose to camp in recreational vehicles rather than in the open. Each morning, they drive their vehicles and horse trailers to the next camping spot, then have a bus or convoy take them back so they can retrace their path on horseback. Participants can bring their own provisions, or, in some cases, purchase meals at a chuck wagon that is also following the trail. The rides converge at Memorial Park in Houston on Go Texan Day, the Friday before the livestock show and rodeo begins. The city closes some roads downtown to allow the riders to reach their destination safely. The resulting traffic interruption cause annual complaints from those who work downtown. The following day, all of the trail riders participate in the parade.

Can you rent a horse or wagon?

Richard John Santorum (born May 10, 1958) is an American attorney, author, politician, and CNN Senior Political Commentator. A member of the Republican Party, he served as a United States Senator from Pennsylvania from 1995 to 2007 and was the Senate's third-ranking Republican from 2001 to 2007. He ran as a candidate for the 2012 Republican Party presidential nomination, finishing second to Mitt Romney. Santorum was elected as a United States Senator from Pennsylvania in 1994.
Santorum served in the United States Senate representing Pennsylvania from 1995 to 2007. From 2001 until 2007, he was the Senate's third-ranking Republican. He was first elected to the Senate during the 1994 Republican takeover, narrowly defeating incumbent Democrat Harris Wofford, 49% to 47%. The theme of Santorum's 1994 campaign signs was "Join the Fight!" During the race, he was considered an underdog, as his opponent was 32 years his senior. He was reelected in 2000, defeating U.S. Congressman Ron Klink by a 52-46% margin. In his reelection bid of 2006, he lost to Democrat Bob Casey, Jr. by a 59-41% margin. After his election to the Senate in 1994, Santorum sought to "practice what [he] preached" and hired five people for his staff who were on welfare, food stamps, or other government aid. In 1996, Santorum served as Chairman of the Republican Party Task Force on Welfare Reform, and contributed to legislation that became the Personal Responsibility and Work Opportunity Act. Santorum was an author and the floor manager of the bill. In 1996, Santorum endorsed moderate Republican Arlen Specter in his short-lived campaign for president. Reporters have observed that though Santorum and Specter differed on social policy, Specter provided him with key political staff for his successful run in 1994. The National Taxpayers Union, a fiscal conservative organization, gave Santorum an "A-" score for his votes on fiscal issues, meaning that he was one of "the strongest supporters of responsible tax and spending policies" during his tenure, and ranked fifth in the group's rankings out of 50 senators who served at the same time.
