From what I've heard, refereeing now at the lower leagues (as in the summit of Sunday League to Non-League) is that much easier in the North West (read: Greater Manchester) due to travel and the number of games, referees have had something of an advantage there compared to London and the South East where one may need to travel 2 hours to get to a game. Some to make that jump from amateur to professional is that bit easier.
Equally, I guess, is it's different being a new referee and abused for £50 a Sunday in Oldham as it is in... Battersea. (Btw what a bloody lovely place that is now.) Plus is being a "top ref" is just more of a thing now, compared to back in the day you had Clive Thomas and then Geoff from his farm in East Anglia...
