Flowers in Wiscasset
To find this cache, you will visit Wiscasset, the self-proclaimed "Prettiest Little Village in Maine," home to beautiful old homes, many antique stores, some good "eats," and on occasion, some ridiculous traffic.
The cache is mere feet from Route 1, with plenty of parking available on the street. The cache, a small, black bison tube. Please be stealthy when retrieving and replace exactly as found!
Good luck and cache on!
