As you know, i've not had a real interest in vulgar oil-funded football over the latter half of the year, so my exposure to Premier League grounds has been somewhat limited. I have been chalking off the non-league grounds over the course of the year, though, so off the top of my head...

23 grounds, i think. Thought it would've been more than that, have probably forgot some.
About 60 games seems right.
* Let's say grounds you had to pay to get into only, not times you watched yer mate play on a cabbage patch hungover on a Sunday morning.
