I hadn't been to Syracuse in a couple of years and don't see Syracuse as a whole lot different than many other cities in flux. There are lots of good restaurants, nice areas, areas in decline, and quick access to an amazing array of cool places. It's not really growing but it's not shrinking much either. It's not within my definition of a dump.
As for the dome, I love how close I always feel to the field. I remember being at the superdome in New Orleans with Texanmark. I was one of 1000 people in a 90,000 seat stadium. Weird day and much more of a dump than SU's dome. I haven't been to a lot of other college stadiums, but think the dome is well suited for SU. It's not huge, right on campus, has the same footprint as Archbold, is historic in its own way, and a great place to watch a game. It needs to be upgraded and is in the midst of that major endeavor. It's not a dump. I look forward to the rest of the games I'll get to see from 302.
I do enjoy having Clemson at the dome. We've been competitive under Dino and really hope that continues. Their visiting fans have largely been a pleasure to hang out with for a day. It's been a great event. Best wishes to them in every game except against SU.
