TRADE UP OR TRADE EVEN. 
This cache is near hole 1 "Newby" of the Walnut Creek Disc Golf Course. Hence the name of the cache "Caution: Flying Saucers"
I felt there was a lack of caches big enough in the area to trade items with, which is one of my favorite parts of Geocaching.
Watch for Muggles.
Please remember to trade up or trade even. Rocks, acorns, and broken toys are not fun trade items.
