I guess this post could go in the "best railfan trip ever" thread, but I'll put it here just because.
Back in 2006 or so Rodger Polley counducted a - rather well attended - tour of the URY from Dragon to Mack. We stopped at the various important points and he relayed a little history about each one at each stop.
I shot this photo from inside what's left of the shops in Atchee.
