Visiting the Lewis and Clark Caverns today inspired me to hide a cache. I would have put it in the park if I could, as I just loved the views. You should go check out the views from the vistas if you get the chance (no access fee, but the gate is not always open).
Should be a fairly simple park and grab; parking is just across the highway. This area doesn't have a lot of traffic, but still be extremely careful when crossing the road. Prize for FTF.
Congrats to MM140 for getting the FTF!
