20yrs ago, Goodison had one of the best dispersal times in the league according to a football research study at the time (they went around all premier league clubs and measured the time it took for local roads to get back to normal after a game). Of course, there are good and bad examples, and a lot also depends on the demographics and make-up of the different fanbases, ie the number of out of towners etc. Hence the difference between Anfield and Goodison on that score despite the relative close proximity. The issues with BMD were obvious from the start..... but so are some of the potential solutions..... and everything will be dependent on whether we can achieve the modal shift predicted.
