A while back, I was vacationing with my family in Playa del Carmen, MX. They had some small Hobie cats you could rent right off of the beach. I approached the palapa where the staff was hanging out. I asked if I could rent one of the cats. The guy in charge started quizing me on my experience. I told him I owned two sailboats on the SF bay and had 25 plus years of sailing. I guess he didnot believe me so he continued to quiz me. I was shocked and came up with this gem. "Amigo, I have forgotten more about sailing than you will ever know". He was stunned by this comment and gave me permission to use this main sail only boat. Good times on the water ensued!
