Strange that you mention that… (and I’m not making this up) …because I was just remembering, for the first time in years, a camping trip I took to a campground near there with my cousin when I was very young. And we went to those caves. And when I got this question and googled it and saw the picture of the brown sign on this page it brought back the memory vividly. Like I found an old photo album in my mind.

So, anyway, good question. That was weird.
