Grapevine Mills Mall is a madhouse, so I wouldn't recommend running around there. However, Airfield Dr. is a great place to test drive cars as the traffic is very light on it. That road is just a short jaunt south down Main st. Main st. iteself is a great stealthing road as you want to go slow through there from the shopping traffic. If the Sonic lot gets full, there is another parking lot directly across the street that serves a Donut shop. As that shop will be closed during our event, the lot should have few if any cars in it.
