Hey LSPTpr,
If your looking for dinosaurs and your going up through Colorado, swing West across Colorado and go to Dinosaur National Monument near Vernal, Utah. It is just East of Vernal at Jensen (wide spot in road). In a full day you could see the main place where they are digging or have large side of hill encased for display and then be sure and visit the museum in Vernal. The museum is wonderful and full of displays that would rival the best in the world. Then you could go over the mountain across Flaming Gorge Dam into Wyoming and up to Yellowstone. Would not be much out of your way and it is a pretty drive. If your looking for dinosaurs, Vernal is the place to go.
OK, my 3 cents worth,,, to long for 2 cents.
