For centuries, travelers have crossed America to explore it, conquer it, settle it, exploit it and study it. Now, a small but righteous crew are traversing America in order to edit it. Jeff Deck, and his friends at the Typo Eradication Advancement League (Teal), are spending three months driving from San Francisco, California, to Somerville, Massachusetts, on a mission to correct every misspelled, poorly punctuated, sloppily phrased item of signage they encounter en route. Equipped with marker pens, stickers and white-out, they are seeking to scourge America's landscape of floating apostrophes, logic--defying syntax and other manifestations of laziness and/or illiteracy.
