My home field, Oakland (KOAK), is quite a bit smaller than DFW but it
has two completely separate towers...

Interesting...

Do you know why? Is there a terrain feature that prevents one tower
from seeing the whole field? Are the towers short?

Some very large Bravo airports here in the east only have one tower,
as the only folks who need to be in the cab are the controllers who
need to physically see the field. Everyone else (approach / departure
/ enroute, FSS, etc...) can be in the basement or even a different
building.
