This is a beautiful new rest stop designed to showcase the history of this agricultural area. Besides a working windmill that actually provides the water for the restrooms, the huge silos are full of historical exhibits and offer a cool place to take a break. As a local graphic artist I volunteered to help with some of the displays, in return the DOT gave me permission to plant a cache as long as it wasn't in a building.
The rest stop is designed so cleanly that it was difficult to find a hiding spot, but you should find it easily while stretching your legs. The cache is hanging on a hook so you can quickly snag it and go to a nearby table to log your find. Please place it back securely so a strong wind won't blow it off.
Please be super stealthy when retrieving this cache! I archived the first one after a muggle employee confiscated it, but he did learn what it was and later put it back.
