Wreck your bike in the alley that has red dog gravel. It's a death of a thousand cuts. It's like broken glass. Red dog is a by product of coal mining. It's the layer of rock next to the coal seam that won't burn. It gets mined with the coal. Local towns used that shit for gravel everywhere. The EPA will fine your ass now for using it.
Growing up. Had one friend push another friend on top of a porcupine. That was funny.Sometime in the 70s, I crashed my bike into an organ pipe cactus that we had in our front yard. That wasn't pleasant.
