Typographical heroes

What traveler has not wished they could fix a sign that says "Taxi's" or "Drive Slow"? [well, this one has anyway].

The Boston Globe reports that "a man from Somerville, Mass., and his friend who went around the country this year removing typographical errors from public signs have been banned from national parks". One of the signs they fixed was 60 years old, proving that bad grammar is not a new thing, but also landing them in trouble with the law.

The moral of the story is: when traveling, resist the temptation to fix signs if that sign is 60 years old and is in a US national park.
