GW,
I did a search for LA Roadster show and it says June 15 & 16th. Is this the same show? (I've never been and first heard about it here from you)
"Our show is always held on Father's Day Weekend in June of each year at the Fairplex in Pomona, Caliifornia.
In 2013, the 49th Annual Show will be held on Father's Day Weekend June 15th and 16th at the Fairplex in Pomona, Caliifornia".
