Speaking of grenades, I used to carry an empty one bought from a surplus store. Real grenade, lever, pin and all just empty. I carried it in a tank bag of an old BMW motorcycle. My fantasy (never realized), was on a hot summer day waiting at a light. The car next to me with windows down blasting Gangsta Rap. I grab the Grenade, pull the pin and toss it through the window of the car and watch the frantic exit. I always smile when I think of it.
