4. Everyone doesn't live at the beach
Some 33 enclaves plus Stanton, with mayors all their own, comprise OC (if you drive five miles in any direction you'll have crossed another city line). The majority of people, it turns out, live in hamlets that aren't filled with wannabe models, faux-sailors, and d-bag bros. (Though, lets be honest -- some people do, indeed, live in those hamlets. Sorry, people.)
5. North County people are not the same as South County people
NC types do backyard BBQs, loiter around the Brea Mall, think driving 45 minutes to Dana Point is a ludicrous idea, and make regular trips to Havasu with their outdoor toys. SC types surf a lot, say "dude" too much, wear khakis with flip-flops and Tommy Bahama floral prints, and get overcharged at South Coast Plaza.
