Tulsa is one of the most screwed up cities in the U.S. in terms of the way it's laid out and trying to get around in it. And, that's if the traffic didn't suck to begin with. I know people who live there who can't find a new address they haven't been to before. Heaven help someone from out of town.
Evidently you haven't been to very many cities as Tulsa really isn't that bad to get around in, especially downtown (except for all the construction and detours). From Main St. east all the streets are in alphabetical order and named after eastern cities ie. Boston, Cincinnati, Detroit, etc. and west of Main St they are named in alphabetical order for western cities, Boulder, Cheyenne, Denver, etc. And yes, finding TK can be confusing to find.
