Is that along the oak grove fork below Harriet?

It's not there but it is along a river.  There are a couple of bridges nearby too.

Read all the clues, I've pretty much told you exactly where it is!  Need another hint?

OK, so is it a trail along the railroad grade north of Carter Bridge Campground that comes out at the bridge by the Fish Creek Campground?

EXACtly, Don got it!  It was the old pre224 before the bridges in the 50s.

What happened to Rob, he was on the right TRACK.

I'm surprised no one complained that it was an old road photo.  I would have. 

I humbly pass the torch.
