Riddle This article was published on 10.06.16 renoletters@newsreview.com.">This marker has stood on the Greenbrae Shopping Center grounds for many years but has been badly vandalized. Plaques in markers around the valley were being pried out for the bronze or copper during the Great Recession, and that may have happened here, too. We have been trying to find out from long-time merchants and residents of the area what exactly was commemorated by the marker, but with little luck. We suspect it may have memorialized the Sparks Airport that once occupied the shopping center grounds—Shelly’s Hardware now occupies the hangar—but no one has been able to confirm it. If any reader has information on the marker, please send it to us at renoletters@newsreview.com.PHOTO/DENNIS MYERS More Local Stories » News Pic Change Sparks theatres and streets close.
