I went off trail on a little adventure. I spent 12 minutes wandering through the woods looking for the Hwy 100 pond... unsuccessfully. I went north off the white trail, but from where I was I should have gone west. Based on the GPS data, I got within 480 feet of the pond. If I'd gone about 300 feet to the west, I'd have been on a small ridge that surrounds the pond. :-(
At least now I know the little creek/stream that runs into the pond, and there's a little animal trail beside it. When I have more time (and if I've told someone what I'm doing) then I may attempt this again.
