Our pals at Wonder Fair can always be counted on to do weird and spooky things for Halloween. This year's "haunted installation" (following on the heels of Cemetery Cinema and Dead End Diner) is called Frank & Stein Inc. Hours are 7:00 to 11:00. Visit the FB event page here. Frank & Stein Inc also has its own unusual website here.
Lawrence Creates Makerspace has a Halloween bash planned with a costume party and music.
And most of the other venues don't seem to realize it's Halloween! Lame.
