I am driving from Atlanta to Yellowstone beginning of may. I know this is a really brought question. But is there anything REALLY special that i should make sure i get to see? I want to make good time in the beginning but i will have some extra time once i am in Wyoming if all goes well. I am up for some light wheeling to get to something really nice. But no way in hell can i get in some tough wheeling and break something. Just putting this out there. Any must visit places along I70 to I25?
