Welcome to the Land of Entrapment. What you need to know depends on what you ride and what want to do. For dirt we have lot and lots of it. Most land in NM is public BLM and Forest Service. The drought is starting to cause the FS to close National Forest areas, so check before riding. The following link may help. https://firerestrictions.us/nm/ There are thousands of trails and roads to ride. The FS has a helpful site for exploring. https://www.fs.fed.us/ivm/index.html Since you are from our neighbor to the east where most of the property is private you will like it where you can ride without asking permission on public lands. Remember much of NM is remote and gas stations are few and far between,and they don't always have gas. Also our dry climate will fool you, take lots of water and stay hydrated.
