Calling all LEGO maniacs: Brick Fest Live!, North America's largest fan-created LEGO celebration, returns this weekend. Keeping with the DIY spirit of the Danish building-block toy company, Brick Fest Live! invites guests to enjoy a staggering variety of utterly unique creations, each constructed with painstaking care. Marvel at life-sized LEGO cities and lovingly assembled pop-culture figures, race against friends with LEGO derby cars down a 35-foot track, and even play a few holes on a LEGO mini golf course. Aficionados can even add to their collections from vendors, who'll be selling new and vintage LEGO sets. From 10 a.m. to 6 p.m. on Saturday and Sunday, August 12 and 13, Brick Fest Live! takes over the Denver Mart, 451 East 58th Avenue, for a weekend sure to delight the whole family. Admission is free for children two and under and starts at $22 for everyone else. To buy yours and learn more, go to events.brickfestlive.com or call 1-866-442-4433.
