Gotta watch out for those livestock trucks as well.
Not a motorcycle related story (I can just image the mess it would have made had a bike been involved tho) One of my friends was cruising on the highway in his convertible Mazda Miata when his car broke down. He pulled over to the shoulder to call for assistance and wait for a tow. A cattle truck drove by....you know, the ones with the holes in the side for the cows to get air and cool off, the same holes that allow air in, allow the poop out.....

Sure enough, a couple of those critters let go when the truck drove by and my friends car, inside and out and all over my friend as well... blasted. Runny cow poopies everywhere!!!
He said the tow truck driver was very nice about it...
I always think about this story when I see a biker on the side of the road in cow country.
