Do not hike cross country under any circumstances. Your vehicle can be easily located by air but a person on foot is almost impossible to find. Watch your engine temperature and stop for awhile if it is overheating. Turn off your air-conditioner if you continue to run hot. Two spares is a good idea.
Mines are extremely dangerous.
Look but don't go near or in them. Respect the environment, don't litter or tear up the landscape. County roads have posted speed limits. Otherwise, you can travel at speeds safe for the conditions. Please use common sense.
