It's beyond me why fish would need a night light? Maybe some of them are afraid of the dark and the larger fish that might eat them? I just though it to be quite unusual to see this structure in this location.
Parking available near the GZ. Lots of traffic on the main highway so please keep an eye on the geodogs and geokids.
As always... dress appropriately when caching, watch out for elf arrows and be alert for rattlesnakes in the warmer months when caching in our foothills and mountains... especially around rock formations. Never use your hand to reach into holes or crevices... best to use a walking stick or some other long item to probe these places. Be forewarned that coords are not always great among the trees and peaks of the area as they often block reception with many of the satellites.
