Thirty-five-year hang-gliding veteran William Armstrong appeared
before the San Diego City Council on May 18 to request that the council consider
creating a training hill at the city-owned Glider Port in Torrey Pines.

"We don't have a training hill for hang-gliding safely anywhere in San Diego,"
said Armstrong. "Years ago, a small hill was constructed and people were able to
learn how to fly hang-gliders from that little hill as a ground-school
experience. We can no longer do that."

Wouldn't a scooter tow setup be cheaper?
