I live in Houston.
Snow? What's that? If it does snow here, all of the overpasses are iced over and the highways are closed so you just stay home and watch the idiots on the news.

Hills? You mean the freeway interchanges? You can see about 25 miles from the top of the big ones.

Mud? why bother. there's always a paved way to get there since most of this place used to be rice paddy or swamp.
