|: : What kind of surface is on that blue ramp?
: I've asked Volker Lux. The ramp is built of wood ans has a painted metal (2 mm) surface.
: Why do you want to know?
I suspected it was a metal surface, but wasn't sure. There is one free public park in NYC that is all wood and sheet metal, too. Thanx for the confirmation. btw...What a great name..."Volker Lux"
