I started out building a quarter pipe inside the garage and I would start outside the house in the street and pump my way in and hit the ramp. I have no clue why may Dad let me build this, but I do eternally thank him.

Then one winter I had the idea to build another quarterpipe and put it inside the garage door opposite the original quarterpipe and thereby have an indoor halfpipe. This was where I first did a backside grind.
