Pajarito is a fun little area. Not much vertical (1,200 I think) but great fall line skiing. I have skied there a couple of times, including last year. It is a "locals" area that was originally built by a club. Never any lift line. You get all the scientists from the LA Lab and their families skiing there, so you often hear Russian, Chinese and other languages in the lift line. I believe they are only open Thur.-Sun., so you can sometimes get unskied snow piliing up for a few days. Unless you are staying in Los Alamos it is out of the way, but within 2.5 hrs you can hit a lot of the good areas in NM. It is in a strange spot for weather, so conditions can be weird. I agree that it does not usually have good early season snow.
