For me, always the London games.....Brentford (new ground), Watford (not been for a few years), then Millwall and QPR......hopefully next season.
I went to Bournemouth for a 2nd leg league cup tie, Pollock came on for his debut, think it was extra time when he came onSwansea as I've never seen us play there and I love the Gower beaches, would make a trip of it.
Bournemouth as I've also not seen us play there and a lovely part of the world too for a longer trip.
Stoke, Cardiff, Millwall, Reading, Brentford, QPR, Wycombe to see mates too.
Sheff Wed out of the more local options.
