N758ZC is a wonderful Cessna Aerobatic 152 airplane.
We've logged hundreds of flight hours together (flight time is logged in hours, not miles); both in the Minneapolis area and on 'cross country' flights.
N758ZC and I have been from Alexandria to Willmar. From Duluth to the Minneapolis/St. Paul International Airport. From Redwood Falls to Red Wing.
I did all my private pilot training in N758ZC
Took my first solo flight in her too.
Since she's an aerobatic we did some barrel rolls and tried a loop or two (much to my instructors dismay since I kept stalling and falling out of the loop)
And took my first (and only) tumble in her.
Once you get the right number - add it to the north and west coords above and you'll know where the cache is.
It's a small so bring a pen or pencil.
