HA!! I've noticed this on bike paths and footpaths (hmmm...why is "footpath" is one word but "bike path" aint'?)! I reckon, dozens of times I've ridden off the road and onto an asphalted footpath or bike path and thought my tyres were flat. I figure the surface underneath isn't as compacted as much as a road because it doesn't have to be. So, despite being a few inches of asphalt, i reckon it can be a relatively soft surface.


I'm gunna write a considered, waffley response to this, so stay toooned.
