Now, the best of RTA's collection is available in book form. Reflecting over a decade's worth of photographing actual mixed-up marquees, billboard blunders and signs of all types discovered along city streets, country roads, major freeways and back roads, CAUTION: FUNNY SIGNS AHEAD features images captured by 95 photographers from all over the United States, Canada, and beyond.

Each page presents a color photograph of an ironic, suggestive, absurd, mislabeled or otherwise amusing sign. Photographed by everyday Americans on vacations and road trips, the signs featured in this collection cover the gamut — from street signs marking the corner of Lonesome and Hardup Road to less-than-persuasive billboards for local businesses like Blue Ball Hotel. Check out the list of contributors!

RoadTrip America's CAUTION: FUNNY SIGNS AHEAD is available through Amazon.com and at bookstores nationwide!

What others are saying:

"Fun signs from the side of the road, shop fronts and those wonderfully-American boards where they can change the message every day. From the rude (Beaver Liquor Inc.), through unthinking juxtapositions (Cemetery Lane / Dead End) to the plain unfathomable (Cat Crap), this is a great read and an even better gift.

—Peter Thody, Leeds, UK

"There are some street signs that cause double takes, restaurant names that will give you pause, and an amazing number of signs that include the word "dump" in an incongruous manner. If you're looking for a gift for someone who loves to laugh, you've found it."
