Hey Jim, welcome aboard! As I mentioned in the original post, my family has a nice little place down there...3 bedrooms, 3 bath, nice kitchen, lots of fenced-in patio/ tent space outside... the only cost will be food/drink related, plus gas of course. there is an indoor fireplace, an outdoor fireplace, a fire pit, a gas bbq, lots of stars at night, and some excellent riding!
The route is I-25 to Walsenberg, then west-ish over La Veta Pass to Ft Garland, and on south through the San Luis valley to Taos. It's all either interstate or state highway, but there is lots of gorgeous countryside. Once in NM, there is Taos, Santa Fe an hour or so away...it's really worth spending some time there! There is a hot springs which is a nice place to go if you bring your significant other, or someone you think might become your significant other.... there are several excellent wineries, good food & good times!
An interesting side-trip, time allowing, would be to head south to Madrid, NM where "Wild Hogs" was filmed, or go ride Route 66 for a ways...
Lets get this thing going!
