I went car camping a week or so ago with some traditionalists and it reminded me of this thread. I was using the trip as a test run (you can never have to much experience setting your tarp up right?).
We took my car and I had brought some things to supplement their gear so when they loaded there stuff in they didn't think much of the little Ion on the side. I helped them set up their HUGE 2 room tent and then pulled my kit out. When I got it out and starting walking off in search of softer ground on of them said, "Oh, you brought a camera. Cool." You should have seen there face when they figure out what was going on!
On another note, when it's starting to get dark and you're getting asked questions about tarp camping then it isn't time to start talking about how tents don't really have much in the way of protective properties. Apparently some 13 year olds don't always sleep well after that.
EDIT: I guess I'm going backwards a bit though. I just bought a 2010 Jam off Gear Trade because it was the cheapest pack I could find without fragile mesh pockets so I can carry more food and insulation. I just wish it wasn't so stinking heavy.
