a few days ago, I read this very well done article by New York Times on Bob Burnquist who build the worlds biggest skateboard ramp.
Basically, he build a 280.000$ ramp on his land in California. They say he build it in the backyard of his house, but given the dimension of the more-than-a-footballfield large construction, the house is rather in the backyard of the ramp.
