The last Mystery Spot presented an aerial view from a downtown building...the Masonic Hall, now the Riverside Arts Center. Building Place, Joe, and BF nailed it! Good spottin', gentlemen!This week we're moving to another part of town. Hmm, what is this regrettably now-vanished building? In past days this was the site of the now-vanished custom of "Flag Day." [hint!] Take your best guess and good luck!
