We took Nick's bike to a shop in Lombard to be serviced. It happens to be next to a Potbelly's, so we also grabbed a sandwich and ate on the patio because it was such a lovely day. As I took this picture, I noticed in the reflection that huge storm clouds were moving in. I quickly gathered up kids and loaded them in the car. About two minutes later it was pouring, windy, and had lots of lightning and thunder.
