Zumba is a trademark, people. You aren't supposed to use it as a noun or a verb ("I heart Zumba!" is not allowed, according to the trademark-usage guide), and you definitely can't just slap the word onto your — or your company's — name. So when you see that magical, legally actionable brand name attached to an event, you know that it's a big deal or someone is going to get sued. As part of their Rock the Stage Tour, two of the exercise monolith's leading specialists, Gina Grant and Tanya Beardsley, lead their Zumba Fitness Mega Master Class
at the Johnson County Community College Fieldhouse (12345 College Boulevard, Overland Park, 913-469-8500). Work that body from 6:30 to
8 p.m. Tickets cost $40 and can be purchased at brownpapertickets.com/232274
