If your crew's interested in the west and, like, guns, the Buffalo Bill museum in Cody, Wyo. is pretty spectacular. Biggest collection of historic firearms I've ever seen in *my* lifetime, plus some other pretty cool exhibits (Plains Indians culture, western art, hunting trophies, Buffalo Bill's life). Would also highly recommend you bypass the I-80 in Wyo and stay north instead -- much prettier driving up there.

Hopefully not being controversial, but I might also recommend doing everything you can to get west of whichever "middle state" you're crossing as quickly as possible (i.e., IMHO, there's not as much to see in Nebraska, Kansas, or the Dakotas). Deadwood and the Black Hills are cool, but things get more spectacular in western Montana, Colorado, and Utah.

Speaking of Utah, if you're interested in fishing and seeing some great scenery, I'd highly recommend you check out Fish Lake. Puts you very near Capitol Reef and the other national parks as well as near some great driving (not too far from Valley of the Gods and Moki Dugway) and offroading (Escalante). And the fishing there is almost always hot.

Have fun,
