Last time I went camping was a long time ago. 4 of us went for 5 days. We had a half barrel of beer and a single package of hotdogs. We survived just fine.
Ok, seriously, that is what we took. We ate the hot dogs the first night fully expecting the 20 people from another area to show up with practically a grocery store. First time camping at this spot, we made camp as the only people around in the middle of the woods for miles and miles. I woke up the next day to find one of my buddies walking down the path eating a big turkey leg. Imagine the shock of finding him eating a turkey leg when we were the only ones around. We were quite drunk the night before and most of us woke up very late and didn't hear the ruckus around the "corner" in the path where a group of 20 or so showed up. I went to check it out and they had several spits going with chickens and turkeys, piles and piles of cases of pop and beer, and enough food to feed an army for a week. Best camping trip I had.
