I live close, too.  Think about it . . . the Triangle is where Rush/State interesect at Cedar along each south to Oak Street.  Think Gibson's, Hugo's Carmine's, Tavern, Jilly's, Whisky, Lux Bar, et. al., and picture the older guys going after the younger women (uhh, providers!)  Women still take their lred ipstick and tag buildings with a big red heart and on the inside write "Welcome to the Viagra Triangle!"
