If you’re visiting Rhode Island, you might be excused for wanting to visit Jerimoth Hill: It’s the highest point in the state.

Unfortunately, you’d be taking your life in your hands. Jerimoth is private property, and it’s owned by a singularly cranky 77-year-old named Henry Richardson, who monitors the trail with motion sensors. Here’s how he’s greeted other visitors:

• Assaulted them verbally (“Shoot all the damn highpointers!” “Get the hell off my property!”)
• Threatened to break cameras
• Started fistfights
• Let the air out of their car tires
• Shot them with rock salt
• Chased them through three states by car

Under pressure, Richardson’s son agreed in 1998 to let hikers visit the highpoint on national holidays. Before that, the 812-foot rise “was considered less accessable than Mt. McKinley.”
