i live in the New Orleans area, and we get hurricanes a couple times a year. It's gettin near the season, we already had a tropical storm. I noticed that after a major storm, out of Lasers lined up next to each other, some of them have barely moved, and some have floated to the other side of the yard and even down the bayou. And it doesnt seem to matter if they're on a trailer or a dolly. I was wondering, does something influence that, or is it just luck? and what can i do to keep my laser where it is?
