As far as I can tell, the biggest Celery Farn Big Years were by:

Fred Weber,  2008: 192

Rob Fanning, 2006: 183

Stiles Thomas, 2006: 175

John Workman, 2006: 172.

You can go to the Fyke website and see Fred's, Stiles', and John's incredible checklists.

Please let me know if I have missed any.

By the way,  eBird makes it much easier to keep track of your sightings and do a BCelery Farm Big Year, but these hand-done checklists seem like works of art to me.
