This is a cool promotion from Good Times: they’re offering buy one, get one free coupons to a number of Colorado Springs attractions to encourage Denver-ites to head down south to Colorado Springs and help our local tourism industry! The tickets are valid through August and include a number of great Colorado Springs attractions, like the Cheyenne Mountain Zoo, Cave of the Winds, the Mining Museum, and quite a few more.
Go here for more information and a list of attractions. (I’m having trouble making out what all the logos for the attractions are, sorry!) You can find lots more things to do in Colorado Springs here.
