thebaldguy has a great idea: take your show around the country! but if you come up here, make it mid-summer. your camera crew probably wouldnt enjoy spending a couple days in mid-winter on an outdoor range with windchills down to -20.
i'd also have to cast a vote for some of the more simple stuff, like maintenance of rifles, shotguns, pistols, as well as some introductions to C&R.
