The parade starts at 1100, registration at 0930. In the past there is somewhere around 150 entries, so however long it takes to get them going. I would say it is over by about 1230, but that depends on your number in the lineup. They try to run current units, then veterans units, then other entries. If you are up towards the front it will be quick, if towards the back it will take a little longer. Hopet his helps.
Amram, sorry about the tire crack. I used to belong to a jeep club and they had a breakdown trophy of an old piston, that was owned by the person with the latest breakdown, until the next victim had their rig go down and that is how it was passed around in the club. The worst one was if you didn't wear your seatbelt, you had to hang a seatbelt with and old cow bell on your rig, until you caught the next victim.
