When you get the chance to get out and stretch your legs a bit.
Sam Correro (creator of the Trans America Trail) laid out a route across New Mexico that takes about 4 days to ride.
It's a really nice ride------mostly real easy stuff--but extremely scenic--------it starts on the Colorado border and end up near El Paso.
I think it's a little over 700 miles long----very little pavement.
Info on the ride can be had at this link.
Here is a link to the story with pictures when I rode it a few years ago.
Some pics of it.
