You can't flip thru piles of US Picture Postcards for long before you run across the The Nicholson Bridge PA ...
... but not every sender is going to write about visiting 'the fair'.
I had to google the bridge to learn:
https://en.wikipedia.org/wiki/Tunkhannock_Viaduct 1) that its proper name is The "Tunkhannock Viaduct"; or,
http://www.nicholsonheritage.org/ni...celebration/ 2) that its 100th Anniversary Celebration is upon us; or,
http://emmrrc.wix.com/trains#!club-boxcars 3) that the commemorative boxcar is pretty much sold-out!
Q/ Anybody going to the party?
Cheers,
