Tons of trees! The NE part of Oklahoma is actually called green country! I live near Tulsa which is one of the most beautiful and cleanest, and greenest cities I have seen. There are trees along all of the highways, all around town, very very green! Now OKC is much less pretty! The pan handle is the part that is very unpopulated and mostly is cattle ranches and 90% of our oil comes from just that part, so this might be the old time dust bowl part you are thinking about.pseub said:But are there trees? I always picture OK as being flat and tree-less.
