When I went to the caverns back in 1992, I don't think that Ethel Merman was singing while I was there. I did not go to Keys Canoes, what is that? The rafting company that you used to raft down the river? I think that I saw the ball of twine in my travels through there..
The Ethel Merman part was at the end of the tour where they had you in this large room and then turned off the lights to show you how dark it is under ground. Well, It was real dark. Then a recording of Ethel singing GBA came on and they projected a flag on one wall. It was cheezyness to the max.
...my family and extended family got in a caravan of about 5 vehicles and went on vacation. ...
We use to do this with friends as well. Get a couple of cars together with only a loose destination in mind just to see what could be seen along the way. My wife and I still do this but have become more sophisticated using the web to plot out a cheezy weekend outing. 

. Just kidding, all in good fun. My wife always busts my chops whenever I want to shoot something. This is what she does -->
Oh, an elbow. Hahaha. LMAO Even your dark curly arm hairs made convincing pubes. You cheeky bugger.
