Third time is a charm

When I go to the airport I usually park in the Economy lots and take the shuttle to Terminal 4. When I return from my trip I take the shuttle back, get my car and exit to the East Valley. The problem occurs when picking up someone at the airport and going back to the office. I am not familar with this route, my office is in downtown Phoenix, the opposite direction of where I live. I took Kim to the airport this afternoon and for once took the correct route back to the office without having to make any detours:) It is really not hard at all, kind of bad that it took three times to get it right.
