TosaFest 2015 kicked off Friday night in the village of Wauwatosa. Organizers say the success of the event has resulted in larger crowds and a need for more security.

There was fight at the fest last year.  Now it's still free to get in, but you'll be required to put on a wrist band to indicate you were admitted through a formal entry gate.

Also, anyone under 18 has to be with an adult Friday night and after 3 PM on Saturday.

“We've grown so much we've embraced an admission policy to help promote the family aspects of the festival,” says John Raisler a TosaFest volunteer.

This is the 40th year for TosaFest which features 30 food vendors, three music stages and new kids activities this year.
