This happens most every wednesday of the week at portland international raceway. It's mostly domestics, but frankly anything that looks old and japanese gets in. I drove my 78 colt right into it last year a few times. I think we need to start getting a larger japanese classic crowd in there. I'll be attending most of them this year with my lancer or my r5 turbo 2. They also let in exotics. It's great fun, and the local z club usually attends.
info and schedule can be found here.
