I don't get the chance to adventure as much as I used to. Fortunately, I can vicariously live through the journeys of others including two adventurers who recently shared what it's like inside the caverns of Cave-In-Rock State Park in southern Illinois.
If you're looking to cool off as the weather heats up and defy gravity at the same time, I know a place in Missouri that maybe should be on your must-visit list. Many who go there jump off the rock cliffs and there's also a natural waterslide.
