My wife is brilliant!
We were driving up Rt 11, a two lane highway in NY, and we were dodging potholes. That's not an uncommon sport around these parts, but I was grumping because they just recently re-paved this road.
Then I wondered aloud if this new process, where they grind up the old pavement and mix it with oils and tars to make recycled blacktop, could be at fault.
She thought for a minute, and said, "Sure! Think about it! When they grind up the old stuff, they grind up all those old pot holes with it!"
Like I said, Brilliant!
