Ribblehead Viaduct

Back from holiday and the backblips will probably be done or at least started tomorrow.
Meanwhile there's the question of my 100th blip. We thought of various ideas which included using the bike wheels, we saw sheep and lambs with numbers on their sides, but number 100 seemed to be lost.
But this was the one place we went today before heading home, and as my first blip was the Tay railway viaduct in b/w, it's appropriate that my 100th should be this one.
There are 24 spans like this.
