Looks like a nice day for a stroll through Central Park and a swim in the Jackie-O Reservoir!

Interesting, we use more electricity (or are more prone to temperature extremes) during the week than over the weekend.

makes sense i guess with all the businesses running mostly m-f and many people and schools off on the weekends.
