Any time something like this happens, I ask myself if having easy public access to these amazing natural formations is worth it. The road network that brings cars in, the taxpayer funded saleries of the park rangers and bureacrats who administer these places, all of this seems like a bargain until an ugly american comes on tbe scene and does their thing.
I sort of wish the TSA could pull back on its bizzare overactively imagined danger passion play, and some of that mojo could go into preservation of things like stalactites and stalagmites.
