Being a "near" genius, about ten years ago I left my canopy's up and hung 5 gallon fuel jug's, floor jack's, and even a nitrogen bottle secured to one post.
The next morning I arrived to a "war zone" which included one inside out "easy up" which was beyond repair, a collapsed 20x10 conduit canopy which was drapped over my race car, and a fallen nitrogen bottle which while still attached to the 1" heavy wall emt (conduit wich was now bent 90 degrees) and left a reminder down the side of the car.
Since then, I have new respect for the winds of Bonneville.
The last big storm we had four or five years ago, I parked my truck sideway's in front of my pit to deflect a few of Slim's sliding PortaPotty's from attacking my race car.
There were plenty of canopy's flying by at a pretty good pace.
I would have snagged a few but was too busy trying to get my own one's down.
p.s. Dan, if my "awning" is not removed, it may clip Jim Jenson's "rabbit ear's" off going by the starting line. If so, He has my full permission to shoot my crew at Sundown..........
