IMHO, Mexico is way too dangerous for tourist travel now. While there are many who will tell you it is only dangerous in certain, limited areas and that tourists are not really targeted this is not really so.

See this story in today's L.A. Times. http://latimesblogs.latimes.com/lano...in-mexico.html

If I am on a tourist trip I would rather no have the bus stopped by hooded gunmen.
