Boondocking areas around Keystone Resort, CO??

ok, thanks for the ideas...just to clarify for me...to me, boondocking is not staying overnight in a walmart parking lot. That is stopping for a quick, late, late night nap. I am looking for National Forest/BLM spots along I-70, to the Moab, UT area. I am a teacher, so we need to wait until Memorial Day week to go.

It sounds like it may be too cold/cool/damp/muddy for Colorado, but may be pushing too hot for the Moab area? Bummer!
