Flutterby™! : Air Cannon

Finding the air cannon.

tldr; An agricultural air cannon began firing every two minutes all night long disrupting the sleep of many in my community. I used Google Maps, three listening posts, and a programmed simulation to pinpoint the field hosting the air cannon. The county tax assessor office identified the land owner. I had a phone conversation with the farm manager. That conversation was coincident with the cessation of the nighttime air cannon. I can sleep again.

Using cell phones for timing.
