hey man, where are you from in oregon? i live in eugene and every park here allows them. i'm not sure about other places, i know corvallis does tho. also, kc knows about a lot of the northern oregon parks so ask him too.
i'm sure kc will talk to you. i just talked to him and he wasn't aware that anyone was tryin to talk to him. and btw, instead of makng a new post, you can just edit your old one by using the edit tool (little pencil and paper button in the top right corner of your post)
Who are these kids? I have AIM you know. hit me up.
And to answer your question about where to ride, it all depends on where you live. If you live up and around portland or beaverton there is a few good parks
