Sounds like you know your way around the flying bit. Raton pass is about 6700 feet, would you fly thru it? Keep in mind that my knowledge of flying is limited to changing terminals, going for FC upgrades, and claiming my luggage before anyone else does.
The Blue Hole is at 4600 feet so I figure the altitude dives at 5000. My Oceanic computer senses the altitude automatically when I activate it once there,
+1000 feet, which is close enough for me as long as I keep it very happy in the Green zone. I think the Colorado and Albuquerque divers always try to kill a few hours before driving home thru the respective passes, and I guess you'd be fine if you just added one more to whatever they usually do. I don't know how much diving, much less altitude diving you've done, so please forgive me if I'm boring you here.
The airport is over near the I-40 truck stop. Let us know if we can pick you up??
