Did some research and questioning, and come to find out that the new owner of the site hates trespassers with a passion. A few urban explorers have been caught. It's the usual shtick, with the "Liability Reasons" and such. The Arapahoe GIS shows that the property is Unincorporated, but it is owned by a company called Linnebur grain & buffalo lllp. I figured out that a new business has been set up on the same road as the base, so I emailed them. What I got back was very stern. (Note that I didn't even ask them if I could go to the base, I just asked for information about the owners and property.) This is the email exactly as is: NO TRESPASSING! Period. That's all I know for now. Things are getting fishae. So tread lightly guys, don't want anyone getting caught and locked up.
(P.S. The base I am talking about is the well-renowned 725-B base near Deer Trail. And if you want, message me for the GIS data.)
