I hear a lot of people talk with nostalgia about old grounds, and while I do agree to a degree it can get a bit over the top.
For example:
Baseball Ground, Upton Park= brilliant atmosphere, proper football grounds. Add Goodison to the list when that goes.
Layer Road, Millmoor= horrible places, better off without them. Add Kenilworth Rd to the list when that goes.
Bottom line is that fans have changed more than grounds. We are now an "audience" who purchase a "product" and an "experience" and who will not really make a sound unless they are "entertained" and will think nothing of booing should things not go well. And although some grounds lent themselves more to atmosphere than others, its mainly fans that make atmosphere
Fill the new style bowls with the rabid, boisterous, loud as hell fans from the 70s and nobody would be saying a word about atmosphere.
