Sprinkler? In March? In Ohio?

It has been a mild winter, which has turned into a HOT spring. Everyone around here keeps talking about how the pools need to open in April. Our temps have been unseasonably warm in the upper 70's and mid-80's. We bust out the sprinkler for Johnny as Auntie Sarah takes Howie to the Whipty Do. Is it summer? Sure feels like it.
