We will be heading to Casper,Wy in mid June for a mission trip. Here is our plan:

June 10- 24

Spartanburg to Nashville,Tn 1 night at Koa
Nashville to Kansas City,Mo 2 night at Koa
Kansas City to Casper,Wy 6 nights at Fort Caspar Camoground
Casper,Wy to Estes Park,Co 2 nights at Yogi Bear's Jellystone Camoground
Estes Park,CO to Topeka, Kansas 1 night at Koa
Topeka,Kansas to Paducah,Ky 2 nights at KOA
Paducah,Ky to Spartanburg,SC

We will be traveling with our 3 children (11,9 and 6). Is there any must see places along the way? We are going to the Kansas City Zoo and Rocky Mountain National Park. I know this trip involves alot of driving,but we drove to Rapid City,SD last summer. This year we are going to be pulling a camper. We have thought about taking I-85 to I-75 to I-24 to get to Nashville to bypass The Saluda grade on I-26 in Asheville. Any thoughts on that? Also has anyone stayed at campgrounds along this was before? I just booked KOA's to be on the safe side.
