If you're hanging around Columbus this weekend, it's going to be hard to miss all the visitors here for The Arnold: www.arnoldsportsfestival.com. So you might as well join them!
The Arnold Sports Festival is now the largest multi-sport event in the country, hosting more than 18,000 athletes competing in 45 different sports, 12 of which are Olympic sports (there are even a few genuine Olympic Trials competitions going on as part of the festival). There's even a film festival http://www.arnoldsportsfestival.com/home/sports-and-events/arnold-sports-film-festival.html going on nearby at the Arena Grand Movie Theatre with high-school entries and professional film screenings.
