St. James's Park

Actually, strictly speaking, neither of these clubs plays at St. James's Park. Newcastle's ground is St. James' Park, and Exeter's is St. James Park. Neither appears to include the full stop either. I just prefer to write it this way.

Any question master who asked which club played at St. James' Park and didn't allow Exeter, or vice versa, would be lucky to get out of the venue alive.
