Part of the problem London Superleague has is that most grounds are either expensive to use, or innaccesable to the average fan, I have mentioned elsewhere about the travelling times to get to grounds that they have used, one of the other factors is that they never stay put long enough. Fans in Charlton & SE London might have started to enjoy RL, but the move to Brentford lost them, the same with North London fans when they played at Barnet Copthall, or Crystal Palace. Get your A-Z of London out and estimate how long it would take to travel between these sites. Try www.tfl.gov.uk and enter the details in Travel Planner. The route changes, parking restrictions, track works etc., soon put people off.
There IS a usable stadium in Wembley, actually, near Wembley. Wasps Ground.
Yesterday my son and I travelled to the Skolars match in North London from a day out at Hampton Court. A bus to Kingston, train to Wimbledon and tube to Wood Green ( before the well received free Skolars bus) took the best part of 2 hours.
It's a big place to cover and fans up north would have a better time
of it if their team transferred to Birmingham.
Having said that subject to a bit of investment in the ground Superleague could do worse than look at Skolars.
Only a few tune stops from Kings Cross which means it's accessible from the NW or NE just as easily.
There was a good feeling about the crowd with plenty of Larndan League Fans in attendance. The place itself has much more of a buzz than the leafy suburbs of Twickenham and is definitely more league territory.
I think there should be a South London team to carry on the development work and there would be no reason why one of the more organised amateur clubs should not be invited to step up to the mark to allow a Superleague club to carry on in North London.
