i'm curious if the people who are upset that it may get demolished are jays fans? I can't imagine that there are any jays fans out there that are asking to save it. It was amazing at its time but there's nothing worth saving here. It's absolutely terrible to watch a game in. I've been to 18 ballparks and it's the worst one i've been to. When the roof is open, it's okay but not great. When it's closed, it's flat out depressing in there. The cost to renovate it to bring it to modern standards would probably cost more than putting up a new park. You would have to remove the hotel, hollow out all the exterior concrete to put in windows and glass to brighten it up and from my understanding the hotel (and all its concrete) hold the roof up on days where the dome is open so that wouldn't be easy to change.
This gives them the opportunity to put in a beautiful park that holds far less people (in the 30-40K range i'd hope). Yes, the skyline will change but it changes all the time anyways. The dome is already blocked if you look at the skyline from the east or west. From the south it's visible but still obstructed a bit.
