Hey there! okay...key points...
Crownpoint is one word

Let's see.
Schools: Bureau of Indian Affairs k-8th (not for only native kids...biligaanas can go to school there too

Then, there are the Gallup Mckinley County District schools. k-12th grades. For Private schools, there are the St. Boneventure schools in Thoreau, NM about 30 minutes South of Crownpoint.
Stores: One small trading post. 86 Octane. Right now $2.07 a gallon approx. Then, Mustang Gas station. 86 Octane. Usually 5 cents or so more than the trading post. There is one BASHAS Grocery store that holds the basic stuff to fill a simple kitchen.
Cafes/lunch places: nothing! pack your lunch
Gallup is an hour away. Traveling West bound on Route 9, there is a 20 mile stretch of road that is being repaved by idiots. Takes an additional 15 minutes to get through there. Traveling South, then West bound using the Freeway, via Thoreau, takes about an hour. Grants is 50 minutes away. If you google maps and go to the satillite pics you can see the road twists!
P.S. the route from Thoreau has a CANYON that gets really scary in snow and WIND. Trucks and 18 wheelers use that road a lot because they are constructing a new BIA school. The gravel pits are near Thoreau, so watch out for gravel rocks in your windshield!
A car would do just fine. 4X4 is a bit better during the bad weather times...
I always chat with the local IHS employees...the visiting Docs seem to like living in the IHS housing complex just fine. They get their groceries and exotic things on the weekends and pop into Bashas for a few needs. If your fine with having a simple life during the week, then living in Crownpoint would be just fine.
Bank/ATM: Banking will need to be handled in Grants or Gallup....BUT WellsFargo has an ATM machine in Bashas and it seems to be the only bank is pretty much in every town around here.
Commuting gets hard on the mind and body, and the winter weather is tough.....but, it's New Mexico...by afternoon all is back in business....
For weekends: Traveling into Farmington, NM is better than Gallup. They have a few things that Grants and Gallup don't have. ig: Target, Sams Club, bigger theaters, Sears (full), Lowes, etc..... Farmington is an hour and fifteen minutes North bound.
Hope that helps!
