Personally, I love road trips, do them as often as I can, and always enjoy geocache breaks along the interstates. They give me a chance to stretch my legs, refill my iced tea, munch on a sandwich I brought along, or, best of all, collect a smiley! I believe every self-respecting remote interstate exit deserves a cache, don't you?
Plenty of space to park here, and this exit doesn't see a lot of muggles, so chances are you'll go unnoticed. Accessible from both directions.
Enjoy!
