Unexpected side effects

Most of the driveways in our neighborhood are asphalt, in various states of maintenance. Ours was in pretty bad shape when we sprang for a concrete replacement a few years ago. It made shoveling the driveway much easier, though sometimes a tad more slippery than the rough asphalt had been.

I just looked out the window to see several kids from nearby drawing on the driveway with chalk. We've no objections, of course, but I wondered why ours would be popular, since we don't have kids that age at home anymore.

Concrete makes a better canvas for chalk art. I'd go out and look at what they drew, but the flu has me down.
