Cache hidden in the Duck lake trail network near a great bridge that crosses Sweetwater creek, as it funnels through a rocky ravine, at the junction of Sweetwater and Cable trails. MacGregor Falls bridge was built by the BOMB squad (Bloody Old Men's Brigade). Just down stream there is the really nice MacGregor Waterfall. There are several different loops you can do and numerous access points to the trail system. The one I listed is the closest.
There used to be a cache here years ago, but it's been gone for a long time and this beautiful special spot needs another one to draw people back.
Container is a small tuperware with a few kids toys. GPS can be a bit jumpy and cache is hidden on the trail. No need to bushwhack.
*** UPDATE 2023***
The MacGregor bridge had been rebuilt a few hundred feet upstream. The cache is still at the same site where the old bridge was and the cache is on the south side of the creek. The coordinates are the same, although the hiding spot it slightly different and clue has be updated to reflect that.
