As someone who lives just down the street from you in Grant Park... uh, please shut up. The talking point should be: the heat in Atlanta is terrible, the traffic is terrible, it's miserable here, please don't move here and make it worse.
In all seriousness though, I agree with you on all points except the weather. What I fear is that the word gets out even more than it already has and we ruin a good thing. The Beltline is a transformational project and I've been rooting for it since the beginning, but lately, with all the growth, I'm starting to get a little concerned that the infrastructure really isn't in place to handle what's coming.
