The good thing about the madjeski stadium is that he built a retail park adjoining so gets the rent from that aswell. Very clever idea. It was built at the right time with the 'out of town' retail parks.
If this idea was put in place at junction 16, it would be ideal for people coming from the south.
As you say Madjeski built it at the right time. If this was done now, with the tide turning against out of town retail, we'd manage to catch the worst time to do it. Forget about Madjeski, that out of town soulless thing they have at Colchester is the model you'd be looking at. The County Ground is fine where it is, the location is not the problem, it needs using properly.
