Back in my bicycle racing days one of my favorite training rides took us up to Mt Baldy Ski Area and on the return trip we'd maintain speed in excess of 60mph for quite a while, including through the turns. It was very common for cars to pull over for us to go by since they couldn't, or wouldn't, maintain that speed through the turns. There are two short tunnels on the descent, and it was a bit spooky the first time through them since you can't see that well inside them, and the thought of hitting a stone at those speeds is unsettling, to say the least - our tires were about 20mm wide (less than 1") with about 120psi pumped into them. We'd hold as deep a tuck position as possible to minimize drag and maximize speed. Great fun.

But to do it laying down on skate wheels? Um....... oh hell, sure, why not!!???
