As hundreds of thousands of people flock to Napa this weekend for the annual BottleRock festival, law enforcement officials are keeping an extra eye on security in the wake of the Manchester concert bombing.
Routine bag checks and metal detection wands were enforced at security entrances, but police and event organizers aren't drastically ramping up security.
"We are aware of people's heightened sense, and we're just there to assure them that we can do everything we can," Lt. Chase Haag from the Napa Police Department said.
BottleRock organizers did not speak about this year's security levels, but they did offer a statement.
"BottleRock Napa Valley works in coordination with local and regional law enforcement agencies to provide the very best in safety measures for our festival guests," the statement read.
Inside the venue, police and private security officials could be spotted. Outside, California Highway Patrol officers with police dogs roamed the perimeter, keeping an eye out for any suspicious activity just days removed the Manchester bombing.
"The events that occurred in Manchester this last week, as unfortunate as it was, it's got some people on edge," Sgt. William Bradshaw from the CHP said. "Again, speaking with most people that have come into the event, they feel pretty comfortable here having the dogs here and again, it's just another level of confidence."
BottleRock attendees did not appear to be too concerned about the security presence or the threat of danger.
"We feel for what happened (in Manchester), but we can't let it affect our processes here," Wyatt Scott from Orange County said.
All tickets to the BottleRock festival happening Friday through Sunday at the Napa Valley Expo in downtown Napa have sold out.
