My career military uncle and his wife, after his 2nd retirement from Dept. of Defense, toured the Western US visiting relatives and visiting archaeology digs.
He and my father prided themselves in being well read, and he probably visited MOAB decades ago.
When in Wyoming, he made a big point to show us fossils near Big Horn National Forest, near where they grew up.

I think that's great!
I'm a geologist, and I was just being facetious. (Several PhDs have commented that despite my penchant for detail and determination to get the science right, I occasionally am too flippant for their tastes.)
It is the curse of loving what you do and having fun, and it keeps morale high among field personnel. I have collected fossils from Nevada to the Carolinas, to Pennsylvania to Montana (and a few up in Canada) just for fun, and the majority of those are in university collections. Only a couple were really museum quality specimens (those are actually quite rare), but the rest are fine for reference specimens and teaching paleontology with (and the slightly more casual handling by students). From Moab (UT) to Craig (CO) is great bone hunting (Dinosaur National Monument is in there, too) and I advised one of my undergrad professors of a bone bed in Colorado, and sent him a couple of very nice teeth I found in a wash. I used the same prospecting techniques one would use with a placer deposit, and tracked the teeth back to a remarkable bed of skeletal debris.
I hope he had fun with that, I was off chasing drilling rigs finding oil.
If they get up this way, there are paleo digs in ND as well, with information available here:
