Ok, invasion is a bit of a hyperbole.
Anyway, this is a real nice shot someone helped us with recently. The mail building is 80' long. The building to the right is really a shipping container for storing our gear. The main shooting area goes out to 100 yards + enough room behind to easily maintain. We have a total of 11 lanes on either side of the main area, and a super nice picnicking area covered by the canopy of leaves.
