Yes I have. Luckily it was a cool morning and I was fully leathered up. It was reminiscent of a 70's "B" movie. Seemed like milions of them with no way to get around the flatbed. In reality there were only a few dozen of them on me and the bike, but I was freeking out to say the least. Once the truck turned they up and followed and I wasn't stung. Lots of cars with their windows up pointing at me though. I am supprised the trucks don't have to be netted.
