Below is a photo of my calibration of the pH meter using the buffer calibration solutions. I picked up the calibration solutions from a store called the New Aquarium near Grand Central, in the city.
On Sunday night there was a strong thunderstorm. The motion camera went crazy and picked up a lot of lightning activity. The shot below is a streak that came down in the woods behind the house. I will check back for the tree that suffered this strike when I return next weekend.
