TULSA - Thousands of people are expected to attend the 41st annual Mayfest in downtown Tulsa this weekend.
Security officers are reminding festival-goers to keep safety in mind.
More than 530,000 people are expected to attend and more than 100 vendors have set up shop.
With so much activity, police say there is the potential for danger.
Nineteen off-duty Tulsa police officers are patrolling the festival by foot and vehicle. During off hours, officers will guard the tents.
Though they say this is typically a safe event, there is also the potential for pickpockets, thefts or other non-violent crimes, not to mention attendees who are intoxicated.
A the same time, officers aren't taking any chances after last month's Boston Marathon bombings.
Big bags and suitcases are not allowed at the festival, neither are coolers.
The free festival continues all weekend, wrapping up Sunday afternoon.
