is that near Burbank?
what day is it on? if its during the week, most people would never make it cuz of traffic.
if we try to do something involving all/most of so cal including LA, OC, and SD (and others), i think a more southern location would be fairer(?) to everyone.
ive never been to Speedzone but ive heard its really fun/cool
http://www.speedzone.com/losangeles.htmlseems like there's a lot to do there. we could make a day out it.
