Wow! Thank you to all who responded to my request for travel advice! I have decided NOT to go to Colorado Springs after Durango on the way to the Tetons.
A bit more about our camping crew...
There will be six of us; my wife and I and our four kids ages 10 - 16. We will be pulling our Little Guy Silver Shadow tear drop with a Nissan NV3500 van. We'll have two small tents as well.
I'm not too concerned about steep mountain inclines or winding roads as our trailer is very light.
Many of you recommend sights and CG's that I've never even thought of exploring. I now need to get out a map and start to research these great options.
Thanks so much!
