This June I spent 8 wonderful day in Cancun. I usually make and annual trip to Cancun in May or June, and I have been to Cancun 9 times without incident. This trip was the same with no beefs with anyone, anywhere, including the hotel, restaurants and tours. Beside going on a couple tours I never left the Hotel Zone and only brought in $500 USD with me. When I arrived at the airport (2-1/2 hours early), the counter agent started to mark my broading pass with diagonal lines. He also tagged my luggage with a orange tag with 4 letters on it. At security, when the agent saw the diagonal markings, I was sent through a seperate line, where I was thoroughly searched. I was also pulled asided and searched a 2nd time at the gate. when I arrived home, I did not have any issues with US customs, and was sent on through as usual. I have been through random searches before but not one that started from the ticket counter or where my luggage was marked. Was this random or am I on a Mexican shit list? Is this an occupational hazzad of being from Colorado (legalized pot state)?
