Boondocking areas around Keystone Resort, CO??

Ok, I agree I might be bigger than normal, but I have heard they are places that I might be able to scout ahead with the tow vehicle and see what is "around the bend", so to speak. We want to be as dispersed as we can...we are looking around the Lake Dillon area and Breckenridge or perhaps a little further west on I-70..

thanks for any suggestions!
