I don't have the exact measurements in front of me, but common sense would tell you that a single chairback requires more width than a marked *** space on a bleacher. So, one would assume we'd lose at least one, if not more, seat per row. With the lower deck being sold out (I think that is what I was told), who gets bumped? Even if the entire lower deck isn't, I know C, D, & E are. Ijustfind a hard time makingthat work logistically.
