On our way to a brew fest last Sunday afternoon a guy pulled out in front of us (proper distance) making a left left toward our car, he gunned his 3/4 ton Chebby and out the back flew about two cases of beer and a 80 quart cooler.
Sometime possin' is costly, not sure how I could have warned the HD heading that way, but in a 25 zone I imagine he saw the debacle ahead as the guy hung a yewie in the road an d head for his load.
Within the next few blocks as we approached the festival I must have seen 10 cop cars in a town that has 4.
I'm sure the were too preoccupied to have seen the beer dump anyway.
As to waving at bikers, bikes, babes et al. I do whenever I can regardless of what they ride. I think it screws with people that have a preconceived notion about Harley riders only waving at Harley riders.
