A couple backpackers who decided to put a site together. Mostly about Hiking & Backpacking. Most of this site contains info about Kentucky -- information on the Sheltowee trace, Kentucky State Parks, National Lands, Scenic drives, the Appalachian Trail, and other outdoor stuff.
Topographic maps. This site has got every USGS 1:100,000, 1:25,000, and 1:24,000 scale map for the entire United States; Alaska (1:63,360) and Puerto Rico (1:20,000) will be coming soon. Just type a place name in the search box and go!
An interactive Website for Applachian Trail thru-hikers.
