Best - Allianz Arena, Anywhere with it's own currency to buy beer is fine by me. Worst - Sorry Hoadie, the Priestfield before re-development, a defender hit a clearance into the old main stand and a bit fell off the roof.
The best grounds I have been to are Wembley Norwich Newcastle Southampton Worst are Aldershot Accrington Exeter Cheltenham Blackpool
Best ground been to Millennium Stadium, shame we got trounced 4-1 off Man Utd and played rubbish. Worst ground been to Grimbsy.
