There is/was a cache or two near LL Bean but not one at the place itself - a bit down the street.............close to Bean - here you go:
Freeport Tavern (GC1GTJK) NorthCumberMouth Cachers (2/1.5) - this one's a puzzle
The Cornerstone (GC1RX5H) Trailblazers May '09 (Logan, Matt, Wylie, Victor) (2/1)
A Muggletown monument (GC1JHGK) Doolittles (2/1)
Again - these are all ones I have personally done nearby - and there is one up the street at the Library GC159BD
Hope this helps. Enjoy!
