give is the result. Asphalt gives more than does concrete, although I believe as temperatures approach freezing, this difference is not as pronounced. -Jeff -Original Message- From: picqc [mailto:[EMAIL PROTECTED]] Sent: Tuesday, August 27, 2002 13:08 To: Mike Prizy Cc: Kurt Bray; [EMAIL PROT

I don't buy it. Fall down on concrete and fall down on asphalt and tell me which on hurts the most. You're wearing shoes that absorb shock and you have insoles that do the same. Drop the golf ball on a piece of foam that is on a layer of air(gel, water, whatever) and see how high the ball bounc

I just did the golf ball drop test and used my mail carrier - who just delivered my September 2002 TFN - as the judge. He said it was difficult to tell, but that the ball seemed to bounce higher from the sidewalk, though I think the rough asphalt surface made the golf ball take an angular path,

Re: t-and-f: Concrete VS Asphalt (was: Why on the street?)

There are both pros and cons to both running on concrete VS running on asphalt. Concrete is harder, therefore giving you a greater chance of injury, but is it really that much harder? A concrete sidewalk is usually flat, whereas most asphalt roads are slightly crowned in the middle, meaning yo
