My best friend lives in Lafayette. We visit often and love that town. It's crappy in many places (main Hwy thru town comes to mind), but the oil money has really helped out in the nice places. There is a bar or daiquri drive thru on literally every corner, even out in the country where my buddy lives (Youngsville/Broussard side of town). River Ranch is an awesome area, as is downtown. I'd move in a heartbeat if offered a good job.
Not to mention the food.
Nobody parties like Louisianans party. lol
