Howdy Folks!
I'd pack up all my guns, including my Judge, the 1911, the .40 Ruger, my XDM-.40, the wife's Px4 Storm .9mm and her little .380 (head shots with that being the last option I'd rely on) and all the ammo on hand and bug out to Buckly AFB. They have lots more guns, and plenty of airmen to guard the place, and plenty of fences, and fighter jets, and heavy artillery, and lots of rifles, and it is only a mile from here. If they deny access to citizens trying to avoid zombies (something I'd find tough to believe given such circumstances, especially when it gives them one more person who can shoot zombies) I'd continue eastward to Wild Horse and hold up there. Nobody goes to Wild Horse.
The thing I believe one might consider avoiding is crowds. Zombies will go to where food supply is plentiful. Why chase two people, capable of terminating plenty of zombies, when they can flood into cities where lots and lots of folks are readily available for consumption. They'd do well in City and County of Denver, where the likelihood of being terminated is not so great, or Boulder where it is darn near unheard of! They could munch to their heart's content, and enjoy little resistence. In Wild Horse, there are few people, hence few zombies. What few there might be can be taken out in fairly short order. After that, hunkering down would be fairly easy until a plan can be devised.
Let the zombies take out those who have no means of defense first, reducing the number of folks competing for WalMarts and similar places where they are apt to seek refuge, and after those locations have been cleared of living humans, seek to hit them so as to restock food and ammo while moving to a new location.
Wild Horse also has the advantages of being far from large population centers, and can be reached on back roads. Scant population out that way would equal few zombies to contend with.
Just my .02
