Beyond serious discussions about high frequency trading and tax-dodging mergers, the Berkshire Hathaway shareholders' gathering also is a weekend of fun for investors and Warren Buffett fans alike.

Sometimes called "Woodstock for Capitalists," the event this year drew about 38,000 people to Berkshire's hometown in Omaha, Nebraska. There's arguably no other investor gathering quite like the annual Berkshire confab.

The event is part-investor meeting, part-Omaha road trip, and part-celebrity sightings—finance celebrities, that is. There was also a 5K road race this year.

The shareholder meeting also draws hundreds of college students and young professionals. They journey to Omaha to pocket some investing and life lessons, and possibly shake hands with the billionaire investor himself.

Michael Corey-Yares, a Truman State University student, trekked to Omaha from Kirksville, Missouri. "It's really fascinating. I'm learning a lot from everybody here," Corey-Yares told CNBC.

He was 13 when he first heard about Buffett. "It's a name that everybody throws around. You hear 'Oracle of Omaha.' Really cool title," Corey-Yares said. "And it's really nice to come here finally and see the meeting."

Weaved into the weekend itinerary are appearances by recognizable brands that Berkshire has a stake in, or owns as a subsidiary.

This year's fun included a 7,000-pound See's Candies lollipop that hovered over Buffett.

Berkshire bought the small, California-based candy company in 1972, and it has since become an integral part of the Berkshire lore and weekend tradition.

See's notably was among the first high quality businesses that Berkshire bought. Previously, Berkshire had focused on undervalued assets that could be bought cheap. The See's acquisition shaped Berkshire's commitment to buying businesses with strong reputations and brand recognition. It's a hallmark investment strategy that has helped create the Berkshire empire, and make Buffett a household name.

See's, part of the Berkshire family, features old-time candies and best sellers include assorted boxed chocolates and lollipops.

And what was the flavor of the 7,000-pound lollipop this weekend? Chocolate.

And the lollipop is in fact real—and among the largest lollipops in the world.

If you favor something more savory, there was the Heinz ketchup truck that featured specially designed Berkshire ketchup bottle labels. "Who can sell more Ketchup?" the sign reads. "Warren Vs. Charlie." That's Charlie as in Berkshire Vice Chairman Charlie Munger.

Other Berkshire weekend highlights can include a pit stop at the local Dairy Queen for a Dilly Bar. Or cruise the Nebraska Furniture Mart or Borsheims Fine Jewelry & Gifts and take advantage of discounts just for Berkshire shareholders.

And if you're feelin' fancy, swing by Gorat's Steakhouse, another local institution. You just might spot Buffett hobnobbing with other key executives including Bill Gates, a Berkshire Hathaway board member and chairman of Microsoft,

Of course there's plenty of Berkshire schwag. A hot seller this year was Buffett and Munger rubber duckies.

The holy grail this time around seems to be a smartphone selfie with Buffett in the background. CNBC's Becky Quicky scored the Berkshire selfie trifectca—Buffett, Munger and Gates.
