I once went to Hershey PA with a group of girlfriends and did the cave thing. The coolest thing about it was learning how to make stalagmites and stalactites myself, haha, I used it as a scien project for the kiddos!
The ones we went to had no such light show and we were the only group, so it didn't feel quite so touristy as that looks, but it also didn't make for such cool pictures!
That sounds quite good the old making them! I mean, I know how they are formed but if someone said make one I would be like, eh?! lol
Yeah, it was touristy as feck in there. And no kids. So everyone was treated to ours gpoing mad,, hahahahah!
