First stop, visitor center and the guy manning the counter is a very chatty local. We got the real lowdown: Coronado’s Bridge, well actually the historical marker got moved so its not at the actual location any more plus what we would see if we did go to the right location is remnants of an old bridge foundation….pretty easy to miss. We didn’t go back. Oh, those old boulder billboards, yeah they are still out on old 66 but vandals have shot them full of holes and painted them full of graffiti. Rats, but we are going to see them anyway. Blue Hole, yes that is exactly as described. It is a artesian well fed lake, actually a sink hole about 80 ft deep with crystal clear water. Folks scuba dive in it. Not us though, 61F is still a little cold for this pansy of a diver! It was beautiful though. Very nicely landscaped around and if it were 95F instead of 60F out today, a cool dip might sound tempting.
