Most anywhere in Trinidad is fine. I have friends in all parts of town and know of no negative neighborhoods. Key here is living where there is water and plenty of it. The negatives are going to be worked out. Keep watching here and you will see that there is a huge number of us 40 and 50 somethings about to take the town back and straighten up the negatives.
I only have heard of 1 murder in town in the 3 years I have been back home. I lived in worse places in Denver for sure. The hospital at this point will NOT meet your needs but that is about to change. Airport depends on your definition. Colorado Springs has a great one and that is about 120 miles from here to the airport. Colorado gun laws are pretty open and can be found on the web. If you are out in the county it really isn't ever going to be much of a problem. Double Barrell of this forum can help you out there. I would be happy to show you the great side of Trinidad any time you like. Thanks for thinking of moving here.
