Hi Mark,
You said, "drive up to Cape May" and I thought there was a tunnel I'm not aware of since Cape May is the southern most part of NJ. Anyway, I'm no expert at Cape May, but we make it a habit of stopping there every time we pass by because we like it so much. We anchor right outside the USCG facility.
Cape May has a vibrant downtown area with good shopping and restaurants. When we were there in August it was packed. I'm sure the crowds have dwindled after school started and it's gotten cooler. Main attraction for us is a walk on the expansive boardwalk, walking and window-shopping downtown, and looking at some of the historic homes in the area. Avoid the big Lobster House restaurant and find a nice little local spot for dinner.
Funny story. We were coming down the NJ coast from Atlantic City (don't go there-you'll be disappointed) with a huge following swell and maybe 30 kts of wind at our stern. We were at the top of the world one moment and surrounded by water the next. Everything was OK until we turned to stbd for the few minutes to get protection from the harbor's breakwall. We got our butts handed to us. Waves crashed into us, things went flying, the boat was rolling, it was a $h!tshow. As we passed the end of the breakwall and resumed our composure a whale watching boat was watching us and called us on the radio. He jokingly asked, "did you see any whales out there?". Wise guy.
