...on the other side of the creek.
Most reasonable folks stroll on the west side of the creek. Why would anybody venture over to the other side? To find a cache hidden by my 5 and 7 year-old children, that's why! And it has CASH from their piggy banks in it! Sign the log!---my children will be checking often, I'm sure, and are very excited.
PS. "Grass is always greener" is not a hint, but you'll understand once you find the cache. ;)
