Hello Steve, Not sure if you are a member of WASAAC? We have the chance of renting an enclosed 6 car trailer from Seattle to Sonoma Ca. and back for $1,300.00 round trip. This would give you the chance to drive your car around while taking in the convention . So far we only have 1 person maybe 2 interested in doing this, there may also be a 2 car trailer available as well, not sure on the cost per car on that one. Let me know if this interests you. Best,
Mark
