Definitely old mines. Some of them are pretty dangerous since they are unmarked. You need to be careful if you are moving fast, like on a quad.

One of the coolest things I have seen was the petroglyphs around a town called Bumble Bee. This area was supposedly used by Pancho Villa and his crew to hide out. There is a waterfall there and is just a cool area in general.

The coolest native american sites I have seen are canyon de chelly and montezumas castle. Montezumas castle has amazing mud rooms, 20 or so, built in to the side of cliffs.

The coolest critters I have seen are bobcats, some huge, and western diamondbacks in the low lands by my house. I have actually had a snake in my house. A non poisonous Arizona sand snake. Scorpions are outside, in my house etc. My dog dispatches them and then plays with them. Probably get 3 or 4 a year in the house.

I have a cabin on Mt. Tritle in Prescott National Forrest that is 90 minutes away door to door. It sits in the pine forrest. There is a huge mine, Davis Dunkirk mine, about a mile from the cabin that is pretty crazy. When you walk in, you can tell the oxygen levels drop and it is dark as all get out. Bats live in there and thats all I have seen in the mine.

I have tried some metal detecting, but have yet to find anything cool, probably because I don't know much about detecting.

There are all sorts of old uninhabited buildings used by old miners around places where I shoot. Some of them are downright creepy. If walls could talk.
