It wasn't terrible as a hub. In the summer the big thunderstorms generally stayed south (mostly) and kept it running even after PHL and DCA (and CLT) went down. In the winter you could deice aircraft at a rate much greater than any other AAA hub. The two long parallels were great for launching and recovering traffic at the same time and 32 was a nice bailout if traffic got too tight when on west flow. Other than the giant bump in 28 (I think? It's been YEARS) the pavement was buttery and the airspace was uncrowded and simple. I flew trips out of there just after the decline started, but it was a great place to operate.
