OK, here's the route Jim & I will be taking to & from Moab. A little longer for sure, but avoids Denver traffic, which is important for Jim...& me too.

From Fargo...

S. I-29 to I-90
W. 90 to Rapid City SD (79)
S. I-79 to Hot Springs (18)
W. 18 (changes to 20) to Orin (25)
W. 25 to Casper WY (220)
S. 220 to Muddy Gap (287)
S. 287 to Rawlins (80)
W. 80 to exit 187 (789)
S. 789 (changes to 13) to Craig CO (13)
S. 13 to Rifle CO (70)
W. 70 to Grand Junction
W. 70 to 128
S. 128 to Moab

We will be going the same route on the way back with planned stops at Mt. Rushmore & Crazy Horse monument (SD) for photo ops.
