hotflashgal and gims,
I bought Wild Bill, my hubby, a GPS 4 Christmas. He searched the NET 4 help in programming the unit: the mioscripting looks like Greek, 2 me. He has such things as gps status on maps, navigational, cockpit, VBig maps; an expert on GPS told hubby about the nationwide scavenger hunt. It's great. There are like 400 finds, within a 10 mile radius of our house. If you google geocaching, you'll discover a whole hidden world out there. By the way, we don't go into caves. I don't think there are many caves in this area. At least I don't know of any. Most caches are hidden in town and county parks. It's kind of an exciting thing to do; it makes the walks more fun! Our lab loves it; because she runs like a deer in the woods.
Have a great day....
