DENVER - Where can you see a Diaper Derby, take a Unicorn Ride, observe a Human Chicken Contest or a Zombie Beauty Pageant? You can see all of these and more at the 3rd annual Denver County Fair from Aug. 9 to 11 at the National Western Complex. Hours are Friday noon to 8 p.m.; Saturday 1 p.m. to 8 p.m. and Sunday 10 a.m. to 6 p.m.

Every year, they try to represent more of what makes Denver special. Attendees will be greeted by a massive T-Rex from the Museum of Nature and Science. The Colorado Train Club is hosting a giant 85-ft long operational model train display. The Forney Museum of Transportation is providing a 20 x 60 display of antique cars and vehicles. The Denver Eye is setting up a fantastic display of vintage photographs and images from Denver's past. And the Colorado Square and Round Dance Council will lead ongoing, interactive demos and lessons.

Local antique dealers will also be part of the fun at the new Denver History Pavilion. Eron Johnson Antiques will be doing public appraisals at scheduled times throughout the weekend, and Denver's Antique Row is an official Pavilion Partner. Blue Ribbon competitions in the Denver History Pavilion include: Best Vintage Scrapbook; Best Colorado Fossil; Best Denver Antique; and Best Family Tree Presentation. The public is invited to get involved and enter, to win ribbons and cash prizes. Entry forms are online at

Other new innovations for 2013 include an expanded Animal Pavilion, with Camel rides and three days of sanctioned dog agility trials. A new Friday evening Art & Wine Reception with a Meet-the-Artists party and wine sampling from local vineyards is on deck. And Dog Day Afternoon, hosted by Channel 9's Kirk Montgomery and his cocker spaniel, Joey, allows attendees to bring their dogs into the fair Saturday 1:00 - 4:00 to enjoy a program of fun, dog-themed events and contests. The Kids Pavilion will now be adjacent to the Denver 4-H Pavilion, and will play host to a special appearance by Nickelodeon's SpongeBob SquarePants Sunday 11 a.m. to 2 p.m.

Viva Denver Day returns on Sunday with a fun line-up of Latino-themed events, now sponsored by Telemundo.
