couple of years back i went to the local flea market and bought six pairs of bright yellow oakley style sunglasses for a group of us coming down to help keep track of our gruop...easy to spot in a crowd and cheaper then losing the real thinggs on the beach and i could wear them swimming....anyway.....a vendor on the beach was a little upset because he wore the same color and said it was what he was known for.....left him a pair, the gaurds at the coco, bartender at for real. and sammy the guy who sold wares next to for real......come back the next year and was remembered for and asked if i was leaving more.....since then i always bring a dozen pair that i order on line very cheap and hand them out on the beach.......and the kids love them as well.......have fun on your trip......peace
