Hey, bigjohn,...I'm down here in southern NM so, unfortunately, I cannot help you out with your hunting in the northern part of the state. The trick to finding Merriams gobblers in NM is to get yourself a really loud crow call and spend the last half hour before full darkness in the evening and the first half hour before full daylight in the morning moving quickly from one location to another, hitting the call with a couple of sharp, loud blasts,.... until you get a gobbler to respond. You will find birds to hunt....if they are around...by doing that!
Stay in areas that have water sources. Probably the 8000 to 9000 ft. elevation levels will be best, but they could be lower or higher, depending on conditions.
Good luck to you and your boys!
