Can someone post where to go in Parris, CA, to find this show?
I'll happen to be in CA at the time and would like to drop in - if
I can find the place.

It's PERRIS, not Parris, and it's on I215 south of Riverside, exit 17.
It's a big swap meet at the Orange Empire Railway Museum, with the gate
opening to the public at 9am, as I recall. There is an entry charge.
Martin has a sales table at Perris on Saturday and offers his seminar
in Buena Park the following day. He sells there too, of course.
