I'm about 45 minutes North West of CO Springs.
There's a few in Sheridan I frequent. There's Colorado Auto and Parts on Santa Fe and Radcliff. They've got the biggest yard in the area with the best prices. There's Svegals, and Jimmy there is an asshat. If you NEED a part he'll jack up the price, and he pulls everything and jacks up the price even more. They do have a ton of older cars and trucks, so some times you can get lucky and find junk yard jewles.
Most of the yards here will sell complete vehicals, but not many take them back. Your best bet for gettin rid of an exploder is parting it out on craigslist, and taking it's corpse to a metal recycling place like Westin Metals (Or Oxford Recycling) on Santafe and Oxford.
As far as wheelin, there's a ton of great low altitude spots in the springs. Tons more in the Rockies.
