Between the previous logs that the contents were soaked and complaints that it was WAY off the posted coordinates, I knew this one needed some owner maintenance. I made up a new cache container and took my boys for a bike ride out to the Trailside Park today. It took me a while to find the cache. I found the remnants of the twisted log that USED to be GZ, but no cache there. I just kept expanding my search and looking in all the likely cache hiding spots, and eventually I found it. There was actually a white-tail deer hanging out near the cache, but it ran away quickly when it saw me.
Replaced with a new, dry, clean cache, fresh log book, a TB, and a bunch of toys (army paratroopers, tanks, jeeps, lizards - stuff my boys picked out). Recorded the new hide coordinates. I let my GPSr sit there and average out for a few minutes, so hopefully these coordinates are pretty good.
