This is a 3-stage Multi-cache.
The first stage is a virtual stage. At stage 1, you will find a sign with information about Fernald Preserve. There is absolutely no need to pass the gate and you can even glean the information that you need for stage 2 without leaving your car (how nice of me). On the yellow sign located here, you will need to obtain some information to move along on your Hobbit quest.
