I'm going to be going to a private outdoor festival in Kansas in about six months. The festival is held in an area without wireless access (no Internet, no cell phones) but electricity/generators are scattered around the site and you can park your car next to your tent for electricity if necessary.

A couple of friends of mine are going to be coming to the festival too, but because we're in different groups we will be camping in different areas of the campsite. We all have handheld CB-like radios, but we were also considering bringing our laptops and setting up some sort of wireless connection between the computers. There are a couple of telephones available, and--among other things--transmitting current photographs over landlines to people who weren't able to make it was one idea we had.

My question is: is there a way to connect just two computers together with wireless (probably 802.11b) without a wireless AP between the two of them?

If not, I suppose we could just use a wireless router in a plastic bag. There's a rather large hill on the site with a telephone pole and electrical connection near the middle, rather ideal for some central wireless AP to sit on and provide access throughout the campsite.
