It's 4.7 miles by car from the entrance of IAG to the parking lot at
our field. As the crow flies, we might be right on the three-mile
boundary, depending on how the airport's air space is defined.

OT... Martin, how far is it from IAG to Lockport?
I was thinking about flying up for the day to see the canal and locks.
Is IAG the closest or is there another airport closer?
