Last month, the Boston Globe reported on a curious rivalry between two mapmakers and their boating maps of Lake Winnipesaukee, the largest lake in New Hampshire’s Lakes Region. Bizer and Duncan Press, both family businesses, are locked in a bitter battle with one another, as each touts their own map of the lake as the best map. Bizer’s Map (above) claims to have charted more buoys, rocks and boating hazards; Duncan Press takes every opportunity to rubbish its competition on its website: see the comparison page and the FAQ. Some of Bizer’s claims seem unimportant, and so are some of Duncan Press’s critiques of Bizer’s map. All the same it’s fascinating to see such a rivalry on such a small scale. [Andy Woodruff]
