I was doing a little research on ballpark evolution and ran across some interesting website, which are shown below.
I had had a short discussion about this with my wife- how parks evolved from wooden to concrete and steel to the suburban style, multi-use stadiums, the newer "retro parks." This discussion was largely precipitated by a discussion of the unique elements of Oakland's Alameda County Stadium during the game there the other night and a proposed new football stadium for Colorado State University in Ft. Collins. Part of the discussion includes moving to making parks more attractive, providing increased revenue due to luxury boxes, premium seating, etc.
Anyway, I found a website that actually discusses both the Cell and Camelback very interesting ways.
The author considers the Cell as the father of all of the modern retro parks, and his discussion/analysis is very detailed and interesting. He also has a lot of nice things to say about Camelback- rating it as perhaps the best park (not just spring training but overall).
