no you dont have to pay to park there.
the meet starts at 6pm so the beach isnt going to be much packed.
and frodo, you went on a "spring break" week. its been packed there for the past month or so, but spring break is over so the beach is dead. i went today at noon at got a spot on the second row, driving right in.
it wont be crowded, and i might show up for a bit before hooters, or just have the hooters meet at the beach until we get kicked out.
