I was there yesterday night and boy was it hilarious. It was like tons of spuds coming from the 500-level, some fan was making them and was letting them float down to the field.
They had one guy who ran out there as fast as he could to crush the spuds, it was epic. When he was running, the fans were cheering him like crazy, this guy was so fast and when he got to the outfield (this is like for the third time after someone had released the spuds, he just started stomping on thme like crazy! It was great!
I don't think it was coming from a condo, it would have had to cross some major streets and have to fall right to the field. Check on Sportconnected, they might mention it and at the end of the week it will probably be in their highlights of the week.
