I'm a fair weather geo-cacher. Hubby isn't into it so I don't do it a lot. I do have a handful of hides in my hometown along a hike/bike trail. The trail starts in town, runs along a lake shore and out to a Corp campground. I had to get permission from the Corp of Engineers but they were really good about it at the local office.
If you're ever near Alma, Nebraska I recommend staying at the Methodist Cove campground and walking the trail into town to catch a couple caches.
