Update (Wednesday, 2:20 p.m. PST): The answer to last week's Picture of the Week challenge--which 43 people got--is the Yellow Bikes program at Burning Man. Under the program, hundreds of these green bicycles (though they are called Yellow Bikes) are made available free of charge to attendees of the Burning Man festival, which is held annually in the Black Rock Desert of Nevada. Thanks to all who played last week, and please come back Thursday for this weeks's challenge.

That's quite a few bicycles, isn't it? And they all look pretty much the same. So what are they doing there? And where's there anyway? If you know what those bikes are, and where they're located, you could win a prize in the CNET Road Trip Picture of the Week challenge.

If you have those answers, please e-mail them to me no later than 6 p.m. PDT 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 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.

Also, for everyone who played regularly during Road Trip 2010, please note that this is the fifth of the weekly Picture of the Week challenges. With Road Trip 2010 officially finished --and therefore no more new Road Trip pictures-- the challenge is now taking place weekly , each Thursday, and the photos could come from anywhere, not just Road Trip 2010 locations. So, please have fun playing today, and then come back each Thursday.

For most of the 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..
