Shibe Park was a very nice park in the beginning, as was old Comiskey; both were allowed to fall apart. Crosley Field became untenable once Interstate 75 was built just across the left field fence. Forbes Field was made less than ideal because of the ever-expanding university campus that had it landlocked. Tiger Stadium remained in use because the Tigers' owners saw the folly in moving to Pontiac with the Lions in the '70s, but the surrounding neighborhood eventually crumbled, leaving ownership dead set against any further renovations by the 1990s. Ebbets Field and the Polo Grounds were of course abandoned by westward expansion; the Mets played at the latter at their inception, but by all accounts the place had been let go, and was in shambles in those days. Wrigley and Fenway are here now because their owners believed in their value and their respective neighborhoods didn't betray them. I agree 100%. With the exception of the Cards, those stadiums ripped the soul out of every team that took one.
