I have to say that on the one occasion I visited Chesterfield in their new stadium, I quite liked it. Whereas I dislike the MK stadium quite a lot. Agree with your like of Rotherham's place though.
I am sure they are considering all aspects, but just a quick plea for us exiles who *have* to drive to the stadium. While there are a whole lot of things wrong with Grenoble Road at least there is enough parking on all but exceptional match days. (The exits are another matter of course!) While I have no real hopes that I will be able to park within 100m of my turnstile entrance as I can at present in the East car park, exiles and away fans *do* need a place to park. Presumably the park and ride is going to be the place - so let's have lots of coaches/busses running between there and the stadium (and consideration given to safe walking routes from there as well).
