spanish peaks or trinidad...
Are you being picked up or need to rent a car?
La Veta is a fine airport to fly into. obviously check the winds. I've been there in a C-152. no sweat.
Other good options are Spanish peaks (4V1) which used to have the cheapest self serve fuel around (havn't checked lately), and crtsy car (I've never used it). It is normally unattended and never busy.
Trinidad (TAD) is also within range and is attended with services. I beleive a rental car requires advance notice. Beware the crop dusters!!!
And if you really need more runway and service options, Pueblo is only 1.5 hour drive to La Veta.
