Authorities say two rocket launchers were among roughly 2,500 weapons exchanged for cash and tickets in the Tampa Bay area.
The Hillsborough County Sheriff's Office says the response to its "Operation Gun Swap" on Saturday was overwhelming.
People waited in long lines at five locations in the county to anonymously trade guns for $75 cash and ticket vouchers for the Tampa Bay Rays baseball team and the Tampa Bay Lightning hockey team.
Authorities say that so many people showed up that they ran out of cash and tickets. Deputies had to distribute vouchers for the same cash and ticket packages.
The sheriff's office says two rocket launchers were exchanged at separate swap locations. Bomb technicians inspected them to make sure they weren't loaded.
