You will find everything you need to find and open Stage 2 in the Stage 1 cache. No special knowledge or mathematical wizardry is required to solve, and is easily done by adults and kids alike. Paper and pen would be helpful to write down what you solve.
There is a parking lot right in front of the stage 1 coordinates and you can easily walk to stage 2. Do not park along the highway even if that is where your GPS takes you!! When looking for Stage 2, if you see poison ivy then don't touch it. The cache is pretty visible and not in PI.
Congratulations to Harlangroom for FTF!!!
