New Mexico Positive Encounter

So i've officially moved to new mexico. Closed on the house today and was out front shutting off the water for the sprinkler system with the garage door wide open. Mind you I had nothing with me saying I actually owned the property, just my car in the driveway and me going about my business with my Sig in full view on my right hip (though right side was to the house). A police car pulls up and stops in front of the house and the officer gets out. As he walks up I ask him which way I need to turn the valve to make sure the water is off so I don't burst a pipe with the freezing weather. He thinks for a minute and then confirms what I had been guessing. I say thanks and he walks down the side of my house. I finish up, go back in and close the garage door. By the time I leave the house a few minutes later he's already gone. I walk around the side of my house where he had been to notice my side gate was open. Most likely he saw the open gate and decided to investigate to make sure nobody was breaking in thru the back (since the house had been empty previously). Not certain if he saw my firearm or not but he never so much as asked for my name, nevermind ID. Not sure he would have even said hello if I hadn't initiated the conversation. Still I was thrilled at both the absence of any questioning and the fact that he noticed the gate open and took the time to investigate to make sure my property was secure. With how crazy New Mexico gun laws are I really wasn't sure how the encounter was going to go at the start (especially since I don't have a NM carry license yet, though I do have reciprocity from other states).
