Famous national landmarks aren't to be messed with, and if you get too close to them, in some cases you can get a ticket. I'll tell you what one man did at a place I visited this summer, so you don't make the same bonehead mistake.
Any guess exactly how hot this "hot spring" is?
We have some great hot springs in Texas that have become swimming holes, but you wouldn't even want to dip a toe into this one. Do you know where it is?
