As you can tell I did this really quick but why not just paint the concrete blue paint on a jays logo like I did, maybe add some other stuff on the outside and it already looks better to me than the plain concrete

The vikings are putting in that ETFE roof the first in a North American Stadium I believe, this is how it's supposed to handle snow I don't know how the RC would handle it but I'm sure they could figure something out
I've always wondered why they didn't do a dirt infield all this time, It wouldn't be that difficult and the benefits for the infield players would be huge. Also yes 100% to the bigger seats.
