Maybe this should be called Long Causeway Rd.....
Anyway, you're looking for a magical sticking box stuck to what it sticks to, which is almost a 1/4 mile long. Check the hint if you need to narrow it down a bit! Don't pull off the road too far, you will get wet...
First to find gets a Crab that we got out of " For Cynthia"! Not a real one...
