I love going on Saturday for the ALMS and other events of the day! I am planning on attending Saturday this year, and Sunday is TBD.
I like the idea of a caravan and mutual parking area on Saturday. Last year I parked off-site in a lot off of 1st and Long Beach...something like $20 but an easy walk into the event.
My son wants to go the the Formula Drift event the preceding weekend, so I may head down for that too...
