Riding and racing motorcycles in Baja is like asking to be searched. Federales like to poke around so I bring stickers and candy to keep them happy. It is not worth it bringing any green stuff down south.
in my younger days Id courier hash all over the Euro in C172 only the Brits were the toughest to trick and funny as hell too hence I charged heaps for a uk run often I'd land at a beach unload then fly off to customs and get searched top to bottom the dogs would go crazy after my 4th trip I always bought some dog food a change of Govt stopped all that then these contractors showed up demanding bribes it didn't end well for the contractors ...lol
