I've only lived in Dallas for 2 yrs (will it will be 2 yrs next months), but I love it.
Shopping is great. I spend a great deal of time at Stonebriar Mall in Frisco

I hear it's really cheap to get a house here. Yes the freeway system sucks here, but I avoid that when I can and take the streets.
But I love it here. When I first moved here, my mom noticed a change in my mood. She says that she's never seen me more happy and alive. She didn't want me to move here at first. She wanted me to stay in Louisisana with her. Glad I didn't.
I love Texas.
(not loving my job at the moment....But I still love Texas)
