Growing up in the area, this bridge was often referred to as "Brunno's Bridge" by the locals. From GZ you will have a view of the Oconto River, and should also be able to see an old silo in the nearby field to the south. Years ago the bridge was a popular spot for jumping off the bridge and swimming. It has since been posted as no diving or swimming, but despite the signs, it's still pretty common to see people recreating here.
I noticed there is a pretty good gap between Oconto Falls and Gillett with no caches. The cache is meant to be a quick park and grab, check the hint and you should be quickly back on your way. The cache size allows for a log sheet, and possibly some really small swag. There is a gift for the FTF inside, but please bring your own writting utensil. The container is not big enough for a pen or pencil inside.
