(Gilly, the Devils Nest doesn't ring a bell at all for olme, are you talking about the right Devils Lake, in ND?)
BRAIN FART ALERT
You are right. I kept reading ND and it finally dawned on me....we didn't drive that far as I remember. So I googled Devils Nest.......and it's on Lewis & Clark in South Dakota. At 56 yo I am going to be so screwed when 70 hits!
