We watched a reenactment...
and viewed the acrobatic air show.
Lesson 1: If you struggle with manual focus with a moving object, you can switch to auto focus once to get an approximate starting point on something about the same distance away , then switch back to manual focus.
Lesson 2: Bring your camera bag (or whatever you use to protect your camera) even if there is only 20% change of rain.
Lesson 3: With air shows and reenactments a longer lens works better…so you can close ups even when you are far away.
