I had recently found a geocache by local cacher Hellnite (The Truckstop Traveller GC5F2F5) and thought how strange it was to be able to see so many people, but yet wasn't concerned about muggles at all. I thought how nice that was and that I wanted to try to find a place or two where I could return the favour to Hellnite and all of my caching friends and family.
This place jumped out at me immediately - I see it every time I drive through the tunnel but wonder how many people actually SEE it. You can actually find this cache without hunting too hard, but I would appreciate it you time your grab between the green lights at the top of the hill.
If you have a minute, sit and enjoy the pace of life all around you - it's nice to be an observer once in a while.
