The dog park is good in the morning when traffic is landing on Rwy 12R. The parking garages are good for both Lindbergh and Humphrey terminals. There is a spot at the very end of cargo road (on the west side) that is good for 12R-30L traffic in the afternoons and somewhat good for traffic taxiing to and from Rwy 17-35.
The airport police are professional and friendly. They may ask for identification. My "Uncommonly Good Judgement" post is by far the exception. Enjoy the visit. Email me through my profile if I can be of further help.
