Question: What is the capacity of the stadium where Seattle's professional women's soccer team played through 2018? Passage 1:The Bad Pass Trail, also known as the Sioux Trail, was established by Native Americans on the border of present-day Montana and Wyoming as a means of access from the Bighorn Basin in Wyoming to Bison-hunting grounds in the Grapevine Creek area of Montana. Marked by stone cairns, the trail led across Bad Pass and was established in pre-Columbian times. After Europeans arrived in the area it was frequented by fur trappers and mountain men, beginning in 1824. Trappers assembled pack trains at the junction of the Shoshone River and the Bighorn River, using the Bad Pass Trail to avoid Bighorn Canyon. The trail ended at the mouth of Grapevine Creek on the Bighorn, from which the pack train could float down the Bighorn on rafts to the Yellowstone River and then to the Missouri and on to St. Louis.
Passage 2:In 1977, following years of legal wrangling over the move of the Seattle Pilots to Milwaukee (to become the Milwaukee Brewers), the MLB awarded Seattle a new baseball franchise, the Seattle Mariners. From 1977 the Mariners played in the Kingdome until mid-season 1999 when the team moved across the street to what is now known as T-Mobile Park, where they continue to play today. The WNBA's Seattle Storm arrived in Seattle in 2000, and played at KeyArena through the 2018 season. With KeyArena being closed until at least 2020 for major renovations, the Storm will play for at least the 2019 season at Angel of the Winds Arena in Everett and at Alaska Airlines Arena on the University of Washington campus. In 2013, Seattle's professional women's soccer team Reign FC, including several members of the World Cup winning US women's national team, opened their first season at Starfire Sports Complex and played at Memorial Stadium in Seattle Center through 2018. Starting in the 2019 NWSL season, the Reign began play on their new home pitch at Tacoma's Cheney Stadium.
Passage 3:Members of Brainstorm continued their musical careers with other bands or in production. Woods later went on to perform as part of the Parliament-Funkadelic collective in touring sets around the world. Sims became the trumpeter for the Sounds of Blackness, which won two Grammy Awards during the 1990s. Bright went on to play trombone with the funk band Cameo for over twenty five years, and later released an album with other former Cameo members Aaron Mills, and Thomas TC Campbell, known as MCB (which was also the title of their album). Trenita (Treaty) Womack performs regularly with the Funk Brothers as well as a wide variety of other artists, and appeared in Standing in the Shadows of Motown (film), an award-winning documentary, as percussionist. Gerald (Jerry) Kent has produced a BMI-affiliated self-published CD in 2006, under the name Kent's Way Overdue entitled Tone Paintings, an original jazz-fusion guitar-based collection of instrumental cuts. He also plays guitar and bass with the IDMR Detroit Choir, which choir was used in the closing scenes of Standing in the Shadows of Motown (film), singing background harmony behind Chaka Khan in a Grammy 2003 winning performance of What's Going On. William Wooten, who joined the band after the first album playing keyboards, now tours with The Dramatics and The Spinners. Lamont Johnson released several solo albums and teaches bass. Renell Gonsalves performs with a wide variety of artists, as a skillful Latin-jazz percussionist (His father was renowned jazz saxophonist Paul Gonsalves, late of the Duke Ellington band). Professor RJ Ross has written and co-produced a number of music projects with well-known artists in California including a 2008 CD "Face to Face".
