4 A local history organization with an upbeat, mildly profane name doesn't approach its topics with dusty, archival pomposity. Its latest program of "amusement and education" is called "Humanity on Wheels: An Evening of Mass Transit Tales." Speakers will explore TriMet's history, adventures and an open mic session will encourage attendees to share their own mass transit stories. Doors at 7 p.m., show at 7:30 Tuesday; free; Jack London Bar, inside the Rialto Poolroom Bar and Cafe, 529 S.W. Fourth Ave.; orhistory.com
