I will be in Portland for two weekdays in August. My hosts will be working during the day, so I'm looking for sports activities to entertain myself with during the day. I found a place to rent mtn bikes, but does anyone have any tips on good places to ride in and around the city? Also I found Ainsworth State Park online as a good place to rock climb--any tips on climbing or how to hook up with lead climbers?
Finally, if the weather doesn't cooperate with sports what would be the one place I MUST visit while there? (I've already done CRG last year.)
