I can't help you with your NM hunt, but I did want to welcome you aboard. I did go deer hunting once in NM but it was so long ago I'm not sure what unit I was in.
Anyway, see ya 'round.

I am from New Mexico. Unit 51 is in the Carson National Forest. I have never been hunting there but know that it is loaded with big elk. My friends that have gone all used horseback. This is going to be a new experience if you have never seen rough country. You may want to visit the nm game and fish dept and see if they will allow fourwheelers in the forest. You are going to have one tough time packing an elk out alone. There are some really long shots so pack nothing lighter than a .270. I would recommend a flat shooter like a .264 or 300 mag. Have a great trip!
