Likewise. I live in Chester (full of scousers) but lifelong Lincoln supporter city of my birth and upbringing.
When I first went to Liverpool as a student I tried to go to the famous Liverpool v St Etienne European Cup quarter final, lock-outs all round the stadium and ended in a crush for remaining tickets/returns. Got talking to the guy next to me, turned out he was from Lincoln too, difference being he'd spent half the day on trains, UI'd spent 30 minutes on the bus. That persuaded me to go home, leave him to it, hope he got in as it was a special night.
People do move around you know, we have things like cars, trains and planes and a need to relocate for college, work and so on.
So don't knock 'plastics' who live away from the team they support, many of the posters on here tick that box so a geniune Liverpool supporter from Lincoln is just that - genuine.
