At the end of the road you will need to buy a $40 pit pass-badge for your wife when you get there. Good for the week. Landsendlynda, your GATE GODDESS should have maps of where you can drive and park as a spectator. You can walk about any where you want, pits, starting line, staging line, impound etc. You will be allowed to drive between down course, pit, lunch wagon, and starting line spectator parking as it's miles between them. Just ask anyone questions.
