Looking for things to do. Have 2 young children, 4 and 18 mos. The Dewey thread has convinced me to stay away from there. I have toyed with going down to OC for a day but really staying in the Bethany area. Recommend activities, restaurants, best times of day to find parking, etc. Also, what's the deal with driving over the dunes? Is there a permit required? I checked out the Delaware Parks website but it looked like the permit was for fishing only? I have an SUV but don't have AWD, so I have ground clearance, is that ok or should I have AWD to drive on the beach?
