Update (Wednesday, 10:06 p.m. Pacific): The answer to today's challenge--which 40 people got--is the Declaration House, also known as the Graff House, in Philadelphia. It is where Thomas Jefferson wrote the Declaration of Independence, though this is actually a reconstruction of the original building. Thanks to all who responded today. And please come back for Thursday's challenge.
This may look like any old brick house, but it most certainly isn't. If you know what it is and where it is located, you could win a prize in the CNET Road Trip Picture of the Day challenge.
If you have those answers, please e-mail them to me no later than 6 p.m. PDT Wednesday (to daniel--dot--terdiman--at--cnet--dot--com, and PLEASE include "Picture of the Day" in the subject line). I'll choose a winner at random from among everyone who sends in both pieces of the correct answer. Please forgive me if you don't hear from me if you're not the winner. I get dozens of responses each day.
Also, I've turned off comments because some people have been posting the correct answers there. I hate to shut down discussion, but I want you to figure out the answer on your own.
One caveat: no individual can win more than two prizes. But at the end of the trip, I'll draw a name from among all the daily challenge winners and give out something a little more substantial.
On June 24, Geek Gestalt kicked off Road Trip 2010. After driving more than 18,000 miles in the Rocky Mountains, the Pacific Northwest, the Southwest and the Southeast over the last four years, I'm looking for the best in technology, science, military, nature, aviation and more throughout the American northeast. If you have a suggestion for someplace to visit, drop me a line. In the meantime, you can follow my journey on Twitter @GreeterDan and @RoadTrip and find the project on Facebook.
