I was talking to a friend the other day, incidentally who lives in Portishead (I used to) but have now moved into Bristol.
We got talking about Severnside. He said quote 'bs3 is where we belong' bearing in mind it would probably be easier for people from that neck of the woods to get to and from games at the proposed new site. He added he would not attend games there out of principle.
So my point being Mr Lansdown...
DO NOT assume you will attract new support from the surrounding area, in fact you may just lose current local (to Severnside) support as in this case.
