I will answer your questions in order: I am, Don't Know, Fun, No, Yes and Yes, Usually No.
Pismo is on literally on the beach in central CA, Normally doesn't get over 80 degrees, it rarely gets upwards of 90-95. There are about 3500 acres of open riding area that can get quite crowded and choppy. The dunes are smaller in size compared to Dumont and there is not a lot of room to get a high powered rail up to speed out there. Great place for quads, bikes, and side by sides.
Huckfest will probably be very busy, if your going to make the trip, get your overnight reservations booked now because they do have a capacity for overnight camping.
