Input: Consider Input: Question: When did the expedition that John Colter was apart of in 1807 begin? Passage:Europeans may have ventured into the northern sections of the state in the late 18th century. Most of the southern part of modern-day Wyoming was nominally claimed by Spain and Mexico until the 1830s, but they had no presence. John Colter, a member of the Lewis and Clark Expedition, was probably the first American to enter the region in 1807. His reports of thermal activity in the Yellowstone area were considered at the time to be fictional. Robert Stuart and a party of five men returning from Astoria, Oregon discovered South Pass in 1812. The route was later followed by the Oregon Trail. In 1850, Jim Bridger located what is now known as Bridger Pass, which was later used by both the Union Pacific Railroad in 1868, and in the 20th century by Interstate 80. Bridger also explored the Yellowstone region and like Colter, most of his reports on that region of the state were considered at the time to be tall tales. During the early 19th century, fur trappers known as mountain men flocked to the mountains of western Wyoming in search of beaver. In 1824, the first mountain man rendezvous was held in Wyoming. The gatherings continued annually until 1840, with the majority of them held within Wyoming territory.

Input: Consider Input: Question: Of the teams Macon played for, which is the oldest? Passage:Macon was drafted in the second round (twentieth selection) of the 1952 NFL Draft by the Chicago Bears and became the first African-American player on the team; he spent two years as a halfback and return specialist. He was the second African-American to be drafted by the Bears; the first, George Taliaferro, was drafted by them in 1949, but chose to play in the All-America Football Conference. With the Bears, Macon rushed for 324 yards and two touchdowns on 70 attempts while catching 14 passes for 49 yards and two touchdowns. On 22 kick returns, he averaged 30.5 yards per return and 5.9 yards on 24 punt returns. He left the Bears in 1954 to play for the Calgary Stampeders of the Canadian Football League. Bears coach and owner George Halas was not pleased about his departure, blackballing Macon and suing him for $100,000. As a result, the Bears refused to acknowledge Macon being on the team. After being out of football for two years, which he spent as a longshoreman, Macon joined the Hamilton Tiger-Cats in 1957 before leaving in 1959 to resume his longshoreman career, but later joined the Oakland Raiders of the American Football League in 1960. With the Raiders, Macon was converted to defensive back, and was tied for second in the league with nine interceptions, which earned him All-Pro honors.
