October 1st ride near Omaha, NE(?)

Looking for a place to ride near Omaha the first weekend of October? Willing to drive 6-8 hours any direction.

We like trail riding / exploring. Not a big fan of sand dunes and the like.

Have neighbor with condo in Georgetown, Colorado, but i’m thinking it’s going to be too cold at elevation that time of year.

Suggestions? Thanks, Daubs
