By just about any measure, the All American Quarter Horse Congress is the biggest game in town.

The largest single-breed horse show in the world runs today through Oct. 29 at the Ohio Expo Center. The All American Quarter Horse Congress draws 650,000 people and generates $285 million for the central Ohio economy. The Arnold Sports Festival, by comparison, will attract about 200,000 attendees and generate about $51 million when it comes to town March 1-4.

More than $3 million in cash and prizes will be awarded to competitors among the 23,500-plus horse show entries. Odds are also good for cash awards to vendors seeking government contracts. The US Small Business Administration and others offer free resources to help secure federal contracts the afternoon of Oct. 10 at the State of Ohio Library. Register online.

Horses aren’t the only four-legged critters at the Congress. Dogs are permitted in certain areas and even have their own Puppy Alley. Dog lovers can also enjoy the first Haute Dog Columbus doggie runway fashion show benefitting Canine Companions for Independence on Thursday evening at The Joseph. 

Dozens of presenters and demonstrations are lined up throughout the Quarter Horse Congress. Seminars and talks for those more interested in two-footed business also abound this month, including:

Be a Mentor, Find a Mentor panel discussion and reception by the Women’s Small Business Accelerator the evening of Oct. 10 at Easton.

Adult Prom 2017, a Mardi Gras-themed cocktail fundraiser on Friday to support Cinderella’s Closet Boutique. CYP Club Cares will be supporting this event as well as Speed Networking with Nonprofits on Oct. 25 at Franklin University.

North Korea, Russia and the Future of U.S. is the timely topic of the Columbus Metropolitan Club weekly luncheon on Oct. 19 featuring Patrick Terrien of the Columbus Council on World Affairs, among others.

As far as central Ohio nonprofits are concerned, there is no bigger game in town than next Tuesday’s Big Give 2017, a 26-hour online giving marathon engineered by the Columbus Foundation. Hard to argue with the sentiment for supporting local nonprofits: Go BIG. Be KIND.
