The Bills comment gave me a chuckle. :)
Oddly enough its not the amount of snow, but rather the severity of it. I was born in Virginia - dad in Florida, mom in Georgia. :) I'm here because pops moved to Syracuse and I lived in Cortland area, before moving here (and a stint for college in AL).
What really WAS the catalyst for downtown was not SolarCity or anything major, but the total opposite.
Chris Collins (R) - despite his negative reputation - started out as our County Executive and in combination with Brian Higgins, balanced our budget and make Buffalo profitable for once after some dark economic times, while Higgins asked Bass Pro its intentions at the for Aud site (previous home of the Sabres). They (after several years of promising to build a mega-store) backed out and we created a ton of smaller projects - not continuing on the path of the "silver-bullet" approach to anchoring the downtown on.
So ... Republican ideas (not dominant liberal thinking) IMHO was the catalyst. Collins comes from the business sector, much like Trump. Mind you, I am not trying to make a political point here - merely a strategic small business / economic en-devour that helped Buffalo get back on its right track.
Mayor Brown is actually a good mayor. Thoughtful even .. but Collins set him up to be - again subjective opinion. I like Byron personally ... and lukewarm on his politics, however ... he has maintained great en-devours here. I just hope he goes into the East Side of Buffalo with as much as we have here as downtown.
I remain optimistic that the leadership we have now, will see the benefits of making our minority populations ... better.
