You are so right. We were there earlier this month and the motorcycles are out of control. They were even taking full advantage of the new sidewalk and abusing it as well. I honestly don't even feel comfortable renting a scooter anymore as much as I love to do that and its a big part of our Negril experience. I try to just stay off the beach at night especially around the late night hangouts where most of the trouble is. As you said why tempt fate, nothing worth that for sure.
Maybe its an age thing, I used to love walking the Las Vegas strip at 3am watching all the craziness. Now I try to be in my home casino my midnight and just don't want to take the chance of getting caught up in anything.
