In 1977 I was in 9th grade and Tim and I went and visited Paul, and rode the ramp that his brother made (Notice it's being braced by the telephone pole!). I think I saw his brother doing wheelers on the top of the ramp once. They would set the ramp up against a wall in the breezeway of the local school to stay out of the rain.
Above is Tim Behrend, he skated and built ramps with me until about High School.
