Hey, I'm looking for any trail suggestions along my way to southern Colorado. My route is via I-40 from
Tennessee. Im looking for a place to ride each day with at least 20 miles or more and difficulty being
intermediate or preferablly advanced type trails. I have plenty of time and I'm not on any time crunch - staying in
my van or camping along the way too. I plan on leaving mid-June.
I plan on (or would like to) hit these states along the way: try to stay reasonably close to the interstate...

Arkansas
Oklahoma
Texas
New Mexico

I'll be in colorado for a week or more and know where to go out there but I'm looking for a few suggestions
along the way, have any suggestions? 20 mile rides and prefer advanced terrain (no greenways plz)
