I think you need a game with cetain factors.
1.Not to far away i.e middlesbough
2.Not to expensive, may but people off i.e west ham or ipswich
3. It needs to be a team with a big allocation, I.e Barnsley, peterbough
4. Easy to get to
5. A stadium with a decent atmosphere
6. A family friendly game i.e not milwall cardiff or west ham
So the possible games i think
Barnsley: family friendly, in the past good atmosphere, cheap
Peterbough: standing, cheap
Brighton: new ground, good allocation
any others?
