Storm clouds with thunder, and some motorcycles carry sound in full HD. Too bad, they don't hear like the dog does, then their hearing wouldn't be as it once was.
Remember please ride responsibly like you were a dog, even if your ride a hog.
HD= Harley Davidson not all motorcycles are loud, not all loud motorcycles are Harley Davidson's therefore it takes an inconsiderate rider to make a motorcycle earsplitting, do take good care, I am listening.
