This cache is part of a series – its theme should become evident rather quickly.
There is a puzzle cache which completes the series.
The terrain ratings in the series have little to do with bushwhacking or changes in elevation, but rather are mostly due to the road conditions. Depending on recent rain/snow, how tall the vegetation is, and what type of vehicle you drive may determine if you need to ditch the car.
Stay off of I-39!
Any good geocacher will be properly equipped. Enough said.
