Fieldtech/Josh-
As someone who has relocated from Lafayette to Houston, you will find a few things you will like.
1.) There are a lot of us here... and I am NOT talking about Katrina refugees.
2.) Housing here IS cheaper for the most part (based on a per sq. ft price) if you know where to look. Stick to the West/Southwest (Katy/Sugar Land)part of town if you have a family. The Woodlands area is nice as well! If you are young and single, look around the Galleria area, but be careful! One wrong turn and the neighborhood can turn on ya! The burbs aren't bad for single people, but being in the middle of it was always so much better from what I remember.
3.) If you are an LSU fan, make your way to Big Woodrow's on Chimney Rock for the games! It is PACKED with LSU fans and is a great time.
4.) There are a few good reminders from home here. There are a few decent restaurants here that will satisfy your cravings and SOME people here are okay when it comes time for crawfish. Stay away from Pappadeaux's if you want real Cajun food, though! Also, Hebert's Meat Market (from Maurice) has a few satellite locations here...
5.) If you are ever REALLY homesick, its just a 3 hour or so drive back for the weekend!
6.) Let me know if you need anything... I'll be more than happy to help out a fellow transplant!
Also... you will find a zydeco hour or two here if you listen hard enough on the radio (just to make the topic somewhat relevant). Maybe some other board members can help on that. I also know that the Big Easy on Kirby used to have Zydeco on Sunday nights, but I am not sure if they are still around and, if they are, if they still have the Zydeco nights.
