NO you can't legally, they just started enforcing this about a 1.5 years ago . The Baja Bush Pilots and AOPA are working on it - but there was a big change over at the agency that run all things aviation in Mexico so it has not been resolved yet.

Ha - I know him well. He got rid of the RV and I think the Cub, and just picked up a helicopter (its hard to keep track

- and just got back from a trip down all over Baja in his Skywagon.
And that is hogwash that Baja is not safe (I'm not including the baja/US border towns). There has not been an incident with any of the Bajabush pilots going down there in well over a decade. I've been all over Baja in my 180 and never had an issue, incredibly nice people. I would/have felt safer walking around Baja then (Chicago, LA, NY, etc) . I even flew the 180 to the mainland of Mexico to a small town near Sonora/Sinaloa border (with the guy GBflyer is talking about) and had no troubles, actually was a trip of a lifetime.
If you are serious about flying to Mexico - join Baja Bush Pilots. Lots of great information and trip reports from people actually flying Baja.
