This is right off the road. This spot is right next to something
that was once there and is probably still there, but you can't see
it. Look for the long neglected plaque and the tall thing next to
it. The area is kind of a mess having been used by construction
crews as kind of a turn-around/dumping grounds. Enjoy the ride to
it.
If you find it (and I'd be surprised if anyone couldn't), come
back here and check out this picture I found of it. Click
here. You'll spoil the surprise if you check out the photo
first.
There is no cache here ... yet
By the way, this "thing" here was started in 1903 just about 100
years ago!
