Some of you are surprised that their are shows in Mexico. Yes, there are a number of bodybuilding competitions in Mexico each year, and quite a fan base there too. At the Arnold Amatuer's, a huge contingent of Mexican competitors competed there, and quite a few compete at the local NPC shows out here in California too.
Yes, Bob is right - different sanction fees, different costs of putting up at a venue, insurance, people, etc.
