The coordinates will take you to a historical marker. Take the short time to read about it because this is probably the only cache that is allowed on Airport property...well, what used to be an airport.
Prior to June of 1942, this was Madisons Airport. Now occupied by South Towne it is not what it could have been.
The coordinates will take you to the marker. From there
project a waypoint
50 feet at 090 and you should come up with the find. Bring your own writing instrument please.
Congratulations to J&K&Kids on their FTF.
