I dunno, I think at ground level it's going to be a big difference.
The topography will have to be flattened. I can see how going from this to a slab of asphalt is big down grade. And lets be honest, the only reason this is happening is so Cowboys can plant a massive tent down and make a sight tone of money. But hey, I guess tax dollars for corporate entertainment profits is a time honoured tradition in Calgary.
Time to start figuring out how I, too can get the city to pay for my infrastructure so I can make boat loads of money.
