One thing that should be mentioned also is that summer days in the northern and northeastern states, even if the temperature is the same as here, won't have nearly as hot pavement as we get in TV. The reason is the angle of the Sun: the further south you go, the more direct the Sun's angle is when striking the pavement and consequently the hotter the pavement will get. It is the reason that lake ice melts in large part from the bottom up. In the early spring in Minnesota even though the daytime temperatures did not get much above freezing (and froze hard again at night) you'd still start to see black "rotten" ice forming below the hard clear ice on top.

All true, but we don't have sidewalks. And heaven forbid your dog accidentally walks on someone's grass, so the asphalt seems to be the default.
