Pre, Will Call & On-Site Registration Details

Pre-Registration:  Save time and Pre-Register your Jeep by Sunday, May 18.  Your registration packet will be mailed to you so you do not need to wait in any lines to pick up the materials you need to participate with your Jeep. More than 400 Jeepers waited in registration lines last year, losing valuable time to have fun with their Jeep.  Those who Pre-Register by May 18 also have the opportunity to save money by purchasing the Festival package and discounted three-day spectator tickets for their passengers.  Some other benefits are also provided only to those who Pre-Register by May 18, such as Invasion dash plaques.  A $3 mailing fee will be added to your Pre-Registration total."

From what has been published on the net about this event it was a very well run and well attended event. I would expect this year's Bantam Jeep Heritage Festival to be as good if not better than last year.
