Would have to agree with EL on this one, see this alot at Hoodsport, a couple of years ago my friend was horsing in a nasty chum there and it came unzipped and his weight came flying back and hit him square in the forehead. It hit him so hard that it damn near knocked him out. After laughing about it for a few seconds i walked over to see make sure he was OK, he was still a little woosy, but he continued to fish. Saw him the next day and he looked like he had been branded on the forehead, it left an exact imprint of about an inch and a half 1/4" weight where it whacked him. the next time we went fishing for dogs i brought him a present, an inflatable football helmet to wear to make sure he would be safe...needless to say it he didn't wear it and we both got a chuckle about it...thats what friends are for... laugh gotta love it..
