This week's "Where Is It?" Mystery Photo proved to be a real challenge for most of our readers.

Part of the address for the location was in the photo but the real key to this one was in the logo shown in the photo. Nail that and the rest was easy.

Just two readers were able to figure out that the symbol shown was the log for the Massachusetts Department of Transportation. With that nugget of info, those two readers coreectly guessed that the location was the State Highway Department Depot at 10 Clark Road.

And for their outstanding guesswork, we will be sending Luna Rossa gift cards to both correct guessers -- Betty Bustin and David Williams.

Thanks to all who participated.
