Mudlark and I spotted it from the last waypoint at 1125hrs!
What a nice little home Forester has! I can't believe this cache has lasted so long, but perhaps closing the road has acted to protect it! Having found "Gnome's Cairn", "Gnome's Outhouse" and "Gnome's Lookout" I couldn't pass this one by as we came through on our Eastern Expedition. Meadow Muffin had to leave after waypoint 1 when he was called with bad news (sorry about your dog...) but Mudlark and I found it easily after a nice walk.
I took a Kinder Surprise figure and egg, and left a Wilson golf ball. Thanks for the cool gnome cottage cache!
