What's wrong with UCA? It's an amazing school with several impressive degree options (including political science).

We also have an outstanding chapter of Sig Ep.

You want it all in AR, right? Well that's where you can get it. If you want poli sci and Sig Ep dropped into your lap without any sacrifices, then you should probably just stay where you are.
