my brother just got back from cancun mex. first he did a shark dive with bull sharks he was surounded by about 20 of them. he said it was a bit scarry especially when they made you take out life ins. before the dive!!! then he hooked up with the assault wepon through the canyon runner (thanks adam) and went 13 for 15 on sails in a half day. he said they were free jumping next to the boat. if your headed down thats the boat to get on.
