Nate, in his mapping mania, has got me into openstreemap.org. It is an open source wiki (meaning anyone can edit it) map of the world. If you zoom in to any place I've lived you will* see some of my "work". (I added the Sandy Hollow campground and bike trail.)
The site is European-based, which is reflected in some of the tagging options. I was tempted to tag Covenant Hall as "amenity: biergarten" just for fun but I resisted.
*the servers aren't uploaded immediately so you cannot yet see all my work
