NEC is next to the airport, multi-platform train station, motorways. They have massive parking spaces and it's possible to expand those, including exits. It is probably the easiest venue to get to in Birmingham, certainly easier than Aston.
It makes perfect logistical sense.
But I appreciate it might not be the best location considering it's a bit far from Aston/Witton. But then again, Aston is not exactly a football mecca. I would wager it would be much easier for most fans to get to NEC than Aston.
So we'd have to address a question of whether Aston is our home, or are we going to be a global club that will be able to attract fans from London that can get to NEC in just over an hour.
