Not sure if anything was set in stone for alignment, but just looking at the ballparks, wondering what people thought of a regional alignment? Traditional NL/AL can't work because we have more AL parks than NL, but this could:
NL EAST (northeastern teams)
Shea Stadium-ff09
Olympic Stadium-oldschool62
Fenway Park-soxfanjohn
Yankee Stadium-MMTDad
Exibition Stadium-xxevilivexx
NL WEST (misc eastern teams)
Cleveland Stadium-oskies
Tiger Stadium-papalon
Atlanta Fulton County Stadium
Busch Stadium-muckles6
Comisky Park-Disco dogs
AL EAST (misc western teams)
Royals Stadium-mmiller989
County Stadium-Zephyr1949
Astrodome-alebenta
Arlington Stadium-redsox666666
Kingdome-kev780
AL WEST (California teams)
Jack Murphy Stadium-slickstick81
Dodger Stadium-tedco
Candlestick Park-Shyster
Oakland Colliseum-brianjw
Anaheim Stadium-billpill30
Just a suggestion. Any thoughts?
