it will be great to see you and your family at geopalooza. camping, tent, trailer, and rv (no hook up) is available right there at the event site. mullet sets up a big pavilion style tent with tables and chairs for dining and a big camp fire. he also rents a portajohn, pink for the ladies.
i think that the only reason johnny needs the confirmation of attendance is to have a head count for the saturday picnic.
geopalooza has always been a family friendly event and there are state parks, swimming beaches, pools, etc. nearby to entertain kids.
