I think there should be donation jars for the food or beverage. I am not saying we need to sell the product. A jar is a simple reminder to help offset the cost for the people who provide the food or drinks. I know for sure that if I had a choice to help out club members or walk a distance, I would definitely buy local.
Plus if you have a standard meeting time at the tent, it would be a good time for people to pick up a bite and something to drink.
I like the idea of a parts list with cell #'s. If you live under a rock and do not have a cell phone or do not giving out your cell #, people could report back to the tent the location of the part you are looking for. Call it a mini parts scavenger hunt or what ever you want but it is a good idea.
Unless we can get some special permission to load a truck and bring it in early, the only real way of moving the items in or out is with the cars. So maybe we need to have a central location to load up supplies to bring in each morning. This would hopefully spread out the burden of a few people. I have a truck and trailer that will be near if we need to stock pile any supplies. We would just need to coordinate the cars each morning to load up for that day. They usually are not to friendly about letting you supply yourself instead of using their vendors. I am sure they would love to find a way to shut down the people outside the gates also.
