We're planning a first-time trip to OBX for a week beginning Labor Day weekend. We just got back from Myrtle Beach and I'm trying to plan the "anti-Myrtle" beach trip -- quiet, relaxing, beautiful. But...I'd also like to be able to walk or bike to dinner. It sounds like Duck might be the place to go for that part of the equation, but I'm not sure how congested things will be that time of the year. What if we stay in Avon -- does that necessarily mean we'd have to drive to dinner?
