Boston-based home and auto insurer Liberty Mutual is launching "Bring Back The 4th," a web-based contest where cities and towns nationwide can compete for one of 10 $10,000 grants to continue local traditions such as July 4th fireworks shows, parades, town cookouts and ceremonies honoring veterans.

Starting today, residents from cities and towns across the country can visit http://www.BringBackThe4th.com to help earn $10,000 grants for their communities.

On the site, visitors are prompted to take a brief quiz on Responsible Moments in U.S. History, featuring questions about people and events that helped shape our nation. Each completed quiz counts as one credit towards the site visitor’s town, and the 10 U.S. municipalities with the most quizzes completed on their behalf will win grants.

Website visitors may take the quiz once, and are encouraged to rally neighbors via e-mail, Facebook and Twitter to visit BringBackThe4th.com and take the quiz themselves.

Liberty Mutual will close the contest on Flag Day, June 14.

"Through our local offices serving customers from more than 400 cities and towns across America, we witness first-hand the special place Fourth of July festivities hold in our neighbors’ lives," said Paul G. Alexander, senior vice president of communications for Liberty Mutual. "With Bring Back the 4th, we aim to help cities and towns sustain those local celebrations that, for generations, have provided a way for friends and neighbors to reconnect, demonstrate love of country, and reflect on the sacrifices so many have made to keep our nation safe and secure."
