Come one, come all! The Onset Carnival is on at Lopes Field from Aug. 12 - 14.

Sponsor Theresa O’Neill said she is holding the carnival as a fundraiser for the Boys & Girls Club of Wareham.

“A portion of the proceeds will go to the Boys & Girls Club,” O’Neill said in an email.

The carnival, put on by Cushing amusements, will feature rides, games, and food. It begins at 6 p.m., and lasts until 10 p.m.
