Very good. If you ever want to do a tour around Henry Hagg Lake... send me a message.
Do check Community Cycle Exchange. They do both begginner and intermediate rides. It be great to have a few more recumbents in the group. Very friendly folk. Most rides start from the downtown Portland.
Also check out OHPV... they do regular rides from I205 to Troutdale or East side Vancouver.

They are a group made up of LWB and vaious hi-racers.
Not sure what distances you're into, but there is also SLug Velo

Never rode with them other than the Rites of Spring ride.
