The following is an experience I had about 3 weeks ago which may or may not be relevant to this subject:
I was walking my dogs in the local park whilst listening to some music. I was wearing a Bills sweater.
A guy on a bike pulls up alongside me pointing to himself...i took off the headphones asking him to repeat what he said.
- "I'm from Buffalo"
I said "I take it you're not used to seeing a guy dressed in Bills gear in a place like Australia"
- "I haven't seen a guy dressed in Bills gear outside of Buffalo"
Make of that what you will.
