About the Container
You are looking for plastic container with a green lid. It's about the size of a grapefruit.
About the Location
The cache is close to the path. It is not necessary to go down the hill. You'll be in plain view of people passing by, so some stealth is required, but it's not a very busy area.
About the Classic Toy Series
The Classic Toy Series is an excellent series of 49 geocaches by 'CandyMan. He published them in May 2017 and then retired from geocaching a short time later.
This cache replaces the original Tonka Truck cache, which was archived by the reviewers in 2018. I made it to fill the space on the map and to keep part of 'CandyMan's work going. The original version had a Bison tube attached to a real toy truck. The new verision is only a plastic container, but the listing includes 'CandyMan's text about the history of Tonka and you can see a picture of his truck in the gallery.
The History of Tonka Trucks (by 'CandyMan)
Just after World War II, three Minnesotans who wanted to manufacture garden tools founded Mound Metalcraft in the basement of a local schoolhouse. In 1947, they acquired a competing company and inherited a toy steam shovel in the process. This gave them the idea of making toys. Using pressed steel, they designed a digger and a working “crane and clam.”
After selling 37,000 units in the first year, the founders abandoned garden equipment and concentrated on making toys. They also changed the company name to “Tonka,” after nearby Lake Minnetonka, and branched out, adding semis, wreckers, dump trucks, fire trucks, and forklifts.
While earning a reputation for durability and realism, Tonka kept up with changes in real-life construction and transportation. The company introduced pick-ups in 1955, a Jeep in 1962, and the bright yellow Mighty Dump Truck in 1965. The latter became Tonka’s best-selling toy for the rest of the century. Hasbro acquired the company in 1991. More than 30 trucks now fill out the Tonka line.
