Feeding the gulls and other wildlife will only contribute to annoying behavior. If animals associate humans as a food source that is when the raid tents, swoop down on people, etc.. Also,once they identify humans as a food source they loose the desire to find food on their own. Wildlife needs a better nutritional diet for their survival in the wild then the proceesed food humans have been accustomed to feeding them .
I've mentioned those three evil banes to humanity before, but it bears repeating here. The mosquito, the deer tick, and the green head fly are all out to get you. They know no fear, there are millions of them, and they never stop.
Mosquito bites leave those itchy bumbs we all love, ticks hang around far too long, and they're both vectors for nasty diseases. I don't care, it's the green heads that I hate. When they bite, it hurts. You can't brush them off either, you've got to kill the little ***ers.
Bug spray helps, but don't expect it to work miracles. I bought a can of spray in the everglades that containes the chemical DEET, which is supposed to make you invisible to the mosquitos. It works pretty good on those bastards, but the green head flys think it's an aphrodisiac or something.
Now, this shouldn't deter you from visiting, but you're going to want to be prepared. Do more bug spray research than I did. Think twice about wandering into mosquito breeding grounds. Be prepared to swat with extreme prejuduce.
There are a few sharks in the deep waters on the beach. This would mostly affect surfers. The sharks only feed in the morning, before 8, and at night, after 6. So don't bother them during dinner! There was someone bitten on Hatteras last summer, so jsut be alert.
Weather conditions can be unpredictable on the Outerbanks in the summer. Make sure you bring plenty of sunscreen and bugspray
