It would be a nice idea to have a "Coventry City Northern Supporters Club".
With the London Supporters Club, now 40 years old and still with an active membership of 80+, the concept works well. Many of the members live all over the south east including Upminster, Hornchurch, Tonbridge, Brighton, Shoreham-by-Sea, Hertfordshire, Staines, Newbury and all sorts of places around London from Leyton to Tootingto Ealing to Croydon to Wandsworth (London is the size of a conty itself)......but it works well because central London is avery obvious default central meeting location and all the public transport is geared up not only for members to meet in central London, but for most members it easy to meet e.g. to Euston to travel together to Cov home games.
The same wouldn't be true of members scattered across the north - if you live in Leeds you'd probably just drive to a game, you're not going to share travel with someone from Manchester, for example. So the "Northern Supporters Club" concept doesn't really work as well, which is a shame.
