Supramania is my jam, I'm never on sf so I don't know, there are a bunch of Supras on this side I can gather together, maybe I'll make a Facebook event, if its already scheduled someone will let me know quick
Checking the forums today (monthly of late) I see Tejon (he's also coordinating Nationals July 8-10 in South Puget Sound) posted this on SupraForums:
" Centralia Meet May 14th Saturday
Figured since no one has set a date and people on other forums asking when let's do May 14th. It's a Saturday, weather should be great and let's have a good meet this year to start it off. I don't remember times but I know people from the north and south like to come to visit so let's start meet at 11a.m. Should help avoid any traffic and not to early for those who enjoy their sleep."
