This is a pretty normal-looking scene, isn't it Except for one unusual thing. What is it, and where is it located

If you know, you could win a prize in the CNET Road Trip Picture of the Week challenge.

If you have the answer, please e-mail it to me no later than 6 p.m. PT Friday (to daniel--dot--terdiman--at--cnet--dot--com, and PLEASE include "Picture of the Week" in the subject line). I'll choose a winner at random from among everyone who sends in the correct answer by the deadline. Please forgive me if you don't hear from me if you're not a winner. I get dozens of responses for each challenge.

Also, I've turned off comments because some people would post the correct answers there. I hate to shut down discussion, but I want you to figure out the answer on your own.

Please note: After this week, I'm putting the Picture of the Week challenge on hiatus for a few weeks while I begin to get it ready for Road Trip 2011. Thank you to everyone who has been playing all these last weeks. I really appreciate it. In the meantime, please keep an eye out for the return of the challenge, coming soon.

For most of last summer, Geek Gestalt was on 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 drove 5,266 miles this summer looking for the best in technology, science, military, nature, aviation, and more throughout the American Northeast. You can follow me on Twitter at @GreeterDan and @RoadTrip and find the project on Facebook. Please look for Road Trip 2011, which will be heading to Europe, coming this June.
