One evening after dark (a few weeks ago), my daughter, two grandsons and I were planning to go somewhere, but when we passed the fairgrounds there were fireworks in the sky. We stopped and watched until they were over. We were there at least thirty minutes. We didn't know what the occasion was but it felt like Independence Day. A couple of other cars pulled in behind us. What a strange, delightful event.
We didn't take note of the date, but I'll bet it was Cinco de Mayo.
