OK, not everyone is a geezer who needs people off their lawn. There are a lot of commercial breaks, halftime, most people get to the stadium with 15-20 left in warm ups. There are plenty of legitimate reasons to want a cell signal in a stadium besides "kids these days" ya old farts.
Get off my lawn, LOL!!! All I want is a good enough cell signal that if any kind of emergency at home they can reach me. Remember the old days when they blasted those announcements over the PA? Some day we will at times harken to the days when we couldn't be bothered at a ball game as being the good old days.
