If you are like me, you have a deep-seated love for water and maps of water. Water is calming and maps make you seem more wordly and cultured than you actually are. Hanging maps all over your house says to visitors (ones that don't know you well, anyway), "Yeah, I regularly go skiing in Whistler and hiking in Patagonia. I definitely DIDN'T spend 14 hours this weekend watching Parks & Recreation on Netflix."
THUS: I am always on the look-out for unique maps. Enter Below the Boat Topographic Maps (Prices vary, Below the Boat): hand-crafted, laser-cut wooden topographic maps of bodies of water and their surrounding areas from ALLLLLL over the world. Notably missing is my hometown lake—Lake Ontario, but I won't bitch too hard. The sea captain of my heart loves these maps no matter what.
