If you are passing through here pay a visit to Thewindandrain.
The best way to hitch in either direction on I-25 is the intersection of St. Francis and I-25. If you are heading to Albuquerque you may also try the intersection of Cerillos Road and I-25, although St Frances still should be better.
North towards Espanola
There is no good spot to hitch north on US 84, but just continue walking past downtown and there will be large shoulders all along to make it easy for people to pull over.
