I went to Amsterdam a few years ago to watch an England friendly. In Rembrandt square I spotted the huge Nuneaton Borough (as they were then) St George that I had seen a few times at England games both home and abroad. It's worth mentioning at this point that we had just been relegated from the prem. I went over to have a chat with the owners and we were having a few laughs, I obviously mentioned that I was a Cov fan.
My understanding of how non league football support works was very rudimentary. I was itching to know which of the local 'big' clubs they followed, so I asked "Who's your premier team"? The question was met with silence and most of them turned away, except for one who offered: "We don't have one, we just support the Boro". "Why, who's yours"? I felt myself diminishing in stature by the response and made my excuse to leave owing to a visit to the clog museum. Ever since I've had a strange, albeit mild respect for them.
