Update (Friday, 12:14 a.m. PDT): The answer to Thursday's challenge--which 100 percent of the 41 people who responded got--is the Penobscot Narrows Observatory, the observation tower that is atop the Penobscot Narrows Bridge over the Penobscot River, near Bucksport, Maine. Thanks to all who played, and to everyone, please come back for Friday's challenge.
Sorry about this grainy image, it is highly zoomed in. If you know what this is and where it's located, you could win Season 5 of the Showtime show, "Weeds"--season 6 premieres August 16, as does that network's new show, "The Big C"-- in the CNET Road Trip Picture of the Day challenge. (Showtime is owned by CNET parent company CBS).
If you have those answers, please e-mail them to me no later than 6 p.m. PDT Thursday (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.
