With the ISO cranked up to 1600, and the lens virtually wide open (hence the lack of depth of field with a long lens), 37174 passes Bucknell on 3 April 2004 with the Pathfinder Tours 1Z50 05:37 Worcester Shrub Hill to Canterbury 'County of Kent' railtour. With such atrocious light I wouldn't normally bother if it was going to be yet another 37/4, but a single 37/0 is always worth recording.
