Building a grocery store is far different than building a corporate campus. The interesting thing is that Amazon already has a presence in a lot of these cities, so they're intimately familiar with the day to day workings. There's not going to be any "sugar coating" by city officials.
1) Austin - Whole Foods 2) Newark - Audible 3) Dallas - HUGE Amazon logistics hub 4) NoVa - AWS location
and on, and on, and on.
Austin has horrible traffic issues right now - look at the other guys on this thread that are from Austin. None of them are eager to have Amazon move there. I would welcome Amazon with open arms.
