Context
I live in the suburbs and don't have a great place to catch vehicles going fast (20-30mph fast for a short distance but until they stop), due to the amount of nearby stop signs. There is no airports close by.
Question
I want to improve my airshow photo shooting skills but they aren't many more for the end of this year. I want to practice panning shots but don't have a great area for it locally. Is there anything I can do to practice for it, or will I just have to try it on cars and slower vehicles?
