I was at Target Field 4/20 and didn't notice any problems as far as lines go for the men's restroom. I didn't realize until after I'd finished there was an additional set of urinals in part II of the room, but I didn't have a line to wait it in. I was in and out in and back to my seat in less than a 1/3 of an inning. Before the game might be an issue as people are slow to get to their seats.
Just saw this one between the Bucs and les Expos from 1970!!! http://www.baseball-reference.com/boxes/MON/MON197009020.shtml Gene Alley hits an inside-the-park grand slam! John Boccabella hits a walk-off HR in the bottom of the 9th!
