chris, there are about 20 of us hangers around phx or near there.
tell your friend to check in the arizona backpacking club, snoop and ask questions around here, or contact me for any info on upcoming hangs that he can "test" some of our products. between me and some friends, there is enough loaner gear to fill a small store.
also, there are a grip of AZ hangers that snoop around the hammock forums and not always on here.. so if he is looking for advice for Places and People, he might go there.
any other info such as gear or its uses, just ask.
