I had to laugh at it, but nooooo! My "shore" is preppy as hell...you see Irish cable-knit sweaters more than wife-beaters. My schoolmates were decked out in khakis and GAP sweaters.
My favorite shore towns are the small barrier island towns...the ones where people ride around barefoot in those big 'beach cruiser' bikes with a huge comfy seat and a big basket on the front. Where everybody either surfs or sails. The ones where, wherever you go, you FEEL like you are at the beach. Those towns are my favorite haunts, to this day.
I feel that the 'Jersey Shore' show types are mainly the tourists!! They do bring a certain element of craziness - a 'height of the summertime' type of feeling - and their antics make for great people-watching, if you have a robust enough sense of humor. Everybody loves to watch the show except when it's clogging up the GSP or peeing in their front yard at 3AM. It's definitely a love-hate relationship.
I remember when I was little, watching the crazies go by in Seaside (aka Sleaze-side). It's an OK town, both honky-tonk and innocent at the same time. Surprisingly pretty natural white quartz beaches. I like to run there in the wintertime when all of the rides are closed. If I want to go to the beach, though, I'll pick Mantoloking (peace and quiet), LBI, Seaside Park, Island Beach State Park (my fave), or further south (down the shooo-oore with the dipthong o), Stone Harbor, Avalon, Sea Isle City, or Diamond Beach to name a few. Asbury Park deserves a mention for the great restaurants.
