Sorry for missing this, was in Cali during July
Yes I have been to this some years back, it is a judged show (fairly tight judging if I remember $20 and pre 1991). The parking lot is partial wooded, so if you get there earlier you can get some shade. A lot of interesting vehicles show up, so it is worth it. I have been trying to get back but weather or schedule has been preventing me. This year is possible!
