I think attendances are up across the board. Look at Mansfield, for example. They used to struggle to get 4000 at home including away fans but have already passed that number in season tickets sales.
But yeah, things are definitely on the up, and last season will have got a whole load of youngsters and peripheral fans hooked.
Our average attendance for the coming season could be the highest in decades, especially if we make a push for promotion. There are a handful of teams that will pretty much sell out the away allocation (Mansfield, Grimsby, Bradford, Stockport, Wrexham) and a few more that will take 1000 or so, so 10k+ attendances could be fairly regular.
Honestly, I don't remember a time when we were so well run, and when optimism for the future was so justified. Good times!
