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.
I dont know. The year the Mariners had seemed so great i dont know if they could top it. But then again i didn't think they could top some of the years the yankees put together before... i'm looking forward to seeing what happens though.
