I got over the serious fireworks in my 20's! We were on Huntington Beach, about half a dozen friends and me, and one of my buddy's was lighting and throwing M80's. Well, because there was nothing for the concussion to reflect off of, it wasn't loud enough for him, so he started lighting and tossing them about 10 feet from us, well, one of the resin plugs they cork up the ends with hit me in the left forearm, and penetrated 1 1/4 deep into my arm (Glad it didn't hit me in the Neck!) took about 20 minuets to flush the crater out and five stitches to close it up. No more of those for me!
