I got one! Traditional Cache

There's no fishing allowed at the nearby fish hatchery.  But we got one (cache) here in July.  We enjoyed our experience so much that we thought we'd share.

You won't have to cross traffic if you're headed to Shelton from the canal.  Satellite reception might be poor.  So, take a visual bearing from the right side and do a little fishing. Do not mess with the sensor in the water upstream. That is not the cache.
