For one, your wrong. Like Corp, I have no stats to back this up, but speaking from experience (went to school there, lot of mates down there, often drink down there) there just aren't that many Latics fans. At all.
For two, "some people have this big hang up about keeping Oldham in Oldham"....oh dear. I actually shook my head when I read that, and wondered if I had read it right. Of course people want to keep Oldham in Oldham....because it's Oldham ffs. I'm guessing you just don't get it.
(For the record, I do see Failsworth as being part of Oldham. But I also think it is a shockingly bad location for a new Oldham Athletic stadium. If it was the other end of Failsworth, near Hollinwood, that would be mile better, but this location seems like a bad idea.)
