Tour the Midwest with the Road Trip Picture of the Day (pictures)

ST. LOUIS -- For seven weeks, CNET readers were tasked with identifying photos in the Road Trip Picture of the Day Challenge. Each week, CNET reporter Daniel Terdiman gave away a GoPro camera to a winner selected at random from among anyone who submitted a correct answer that week. And at the end of the seven weeks, Terdiman selected two grand prize winners who were tied with the most correct answers during the challenge -- with 47 out of 49 each. Each won a complete GoPro camera package.

Here are all 49 daily photos, and the answers, which came from Illinois, Indiana, Ohio, Michigan, Nebraska, Missouri, Iowa, and Wisconsin, as well as Germany, California, and New York. Thanks to everyone who participated in the challenge this year, and to everyone, please come back next year for the 2014 CNET Road Trip Picture of the Day Challenge. You could win some great prizes.
