The wife and I did Enchanted Rock about two years ago, left the kids with the Grand Parents since they were waaay too small(1 and 3).  There were a few hams at the beginning, but as we got further along the incline they started dropping off.  We climbed down and into some of the caves/caverns and once again, no fats.  Then we took the long way around, getting a little lost and realizing we were about a mile off the trail/common areas.  It was cool though, we just hiked it and took pictures with my DSLR.  Once we were all done, we got to check into the B&B in Fredericksburg and then went out for a few drinks with the locals and a nice dinner.  Then we went back to the room for some more 'exercise.'  Funny thing is, I didn't see many hams out that evening when we were out eating.
