I reserved a 15 passenger van leaving from the Dallas area on Thursday July 26th at night and coming back on Monday 07/30/07. The cost of the van +a trailor is around $530 +gas. Split between 13 people. Right now our van is full but i am having alot of people email me wanting in on it. Let me know if you are wanting to carpool from the Dallas or Houston (because you will have to drive through Dallas) because maybe we can get something arranged with all of you riding together....
