Old factory buildings, redolent of rusted machinery and children working 14-hour days, are inevitably creepy. And one of the creepiest places on Halloween will be the old Rainier Beer plant in Georgetown. The 1903 brick heap, with its monolithic façade and tall, foreboding windows, is particularly eerie. It’s like a frowning street sentinel with the visage of John McCain: old, scarred, venerable, and deeply pissed off. Inside its abandoned rooms, tonight and Saturday, members of Ensemble Sub Mesa and Annex Theater will be staging their very unconventional spook show, the Haunted Brew House Tour. It’s a one-off production by Theatre off Jackson, likely in the same spirit as Annex’s oft-repeated Halloween show Ghosty, which transformed empty houses into rooms where ghosts couldn’t be freed until the cause of their obsession was revealed. Tours depart hourly.Rainier Cold Storage Brew House, 5900 Airport Way, 340-1049, www.brownpapertickets.com. $10. 6–10 p.m. JOHN LONGENBAUGH
