I've worked out that I've seen Fulham, Crusaders, Broncos and Harlequins play home games at 12 different grounds in London. If I go tomorrow, which I'm by no means certain that I will, Esher RFU ground will be the 13th. I wonder how lucky it will be.
The grounds out of interest are:- Fulham, Stamford Bridge, Crystal Palace, Chiswick Poly, Barnet Copthall, Wealdstone, Hendon, Brentford, Charlton, Kingstonian, Stoop, and Leyton Orient.
Before some one says I missed out Gillingham. I refuse to accept Gillingham as a home ground for a team with 'London' in it's name.

But we did play a home game there, and will again this season.

But Barry's post was about grounds in London - Gillingham isn't in London

London Broncos.................are you listening?

Wow thanks for the geography lesson!
