I'll be there.
I was there (the North Shoot Location) today and had some fun by myself! 200 rounds through the XD and 150 through the M4. Sweet!
It isn't that hard to find. Take I-25 north to Hwy 66. Take Hwy 66 west to the end (pass through Lyons). At the end, make a left onto Hwy 7. Go 13.4 miles. It is near the intersection of Hwy 7 and Hwy 72 (Hwy 7 mile marker 19). There is a callbox there for a landmark. It is across the street from the callbox. There are some signs and an embankment to prevent vehicles from going in there. Climb the embankment, and you are at the location.
