Nah, it was a nice park in the early 90s, especially before Camden Yards reinvented stadiums. Who gives a crap about the foul territory? I went to probably 60-70 games there (definitely seen the Sox play there more than at Fenway) and I never felt it made a difference to my experience other than seeing some more foul outs than usual. Which didn't bother me, pitcher's parks are a good thing in my book. The difference in foul territory only became comical when teams built new parks and teams like the Sox with old parks began to
Natural grass, real bleachers, a hand-operated out-of-town scoreboard*, good and diverse food options (the first cheesesteak I'd ever eaten in my life), clean, comfortable (for a 50 year old stadium, the leg room is still really good). You can get there without a car too. You think about what ballparks were like in 1992 and there were only a handful of parks in the majors that ticked off all those options. The view of the Oakland hills was just the cherry on the top.
The problem with the park has always been Mt. Davis. Both in that it exists at all, and that the city and county have clearly had buyer's remorse ever since and skimped on maintaining the Coliseum. That's led to all the things people don't like about it.
The A's will get a new park and that's great, but I can still go to the Coliseum, get a pretty decent seat for under $20, get a dog and a beer, and have a very comfortable afternoon/night watching baseball. That I have to piss in a trough doesn't matter because I don't go to ballgames to piss in private.
*You might think who gives an F, but Candlestick used to show
out of town scores (to the left of the main scoreboard) on a loop that seemed to take forever. I remember my dad taking 10-15 minutes to find out the Red Sox score because he'd miss it, give up waiting and watch the ballgame, then try to catch the score again, miss it, so on and so forth. Meanwhile it was just *there* at the Coliseum.
