BIKE BALL—The Community Cycling Center is Portland’s foremost bikey do-gooder, with programs that get bikes to needy kids and adults. And for the second year running, you’ve got a chance to contribute to the center’s good work with dancing, drinks, music, and bikes. The swanky Bicycle Ball fundraiser pops off this evening.

SPORTS BALL—Everyone loves an underdog. Portland better love an underdog. That’s what the Blazers are this year, especially up against perennial title contenders the San Antonio Spurs. Socking them (and that traitor LaMarcus Aldridge) in the mouth would feel real good this early in the basketball season. BOBBY ROBERTS
