Or you do what thousands of others in non-Southwest cities do.. drive to a Southwest city and then catch their preferred airline.
I drive to CLE (2 hrs OW) all the time, pass up the Continental non-stop, fly right back to PIT, and onto my final destination.
I also drive to CMH (3 hrs OW). It's all up to how much you value the time lost driving, fuel, depreciation on the car, etc vs the difference in fares.
