1. Rutgers Gardens, a secret garden hidden between highways

4. The Haddonfield dinosaur

The first full dinosaur skeleton to be found in North America was discovered in 1858 in Haddonfield, New Jersey! Bet you didn't know that. While the skeleton is currently on display in Philadelphia, Downtown Haddonfield commemorates its paleontological notoriety with a life-size dinosaur model.

9. The secret menu at Jersey Mike's

Though this shop isn't just a Jersey chain, it got its start in Manasquan, and there are 49 locations in The Garden State. Try the Cancro Special, with roast beef, provolone, and pepperoni, all grilled and toasted until the cheese is melted perfection. Yum! Here's a guide to their secret menu.

10. Sybil's Cave

Located in Hoboken, this cave was once a popular tourist attraction, but is now gated off. Still, the site has some interesting history: an unsolved murder here inspired Edgar Allen Poe's "The Mystery of Marie Roget." Though the cave is closed, you can still see the exterior while walking along the waterfront.

11. Duke Farms

12. Coffee that's out-of-this-world at Grover's Mill Coffee Co

If you're a regular reader, you're probably aware of the Grover's Mill alien invasion scare of 1938. We've actually covered the monument in a previous article, but recently discovered this alien-themed coffee shop. It's dedicated to the Halloween radio broadcast of War of the Worlds, which people mistakenly took as fact. Bizarre! But great coffee. Visit their website for more information!
