Can't say enough good things about this cache; well-laid out and great use of the park. Each waypoint was its own challenge. It does pay to bring a calculator along with you, or at least a 9-year old who still knows how to do math. When we got to WP5 we started to panic thinking we needed to do some complex algebra...holy cow, do we even remember our order of operations? Then we realized that each parentheses was a single coordinate number and not a multiplication indicator. Whew! That made things easier.
Also, what a great winter day to do this cache. About an hour trek in the falling snow and moderate temps. Lots of muggles about but with two kids along we had plenty of cover.
And to top it all off, to find a cache that stumped team Marc, Miata and gizfinder! Boo-yah!!!
