REDNOVA -- Apr 27 -- Lock and Key Events turn an evening at a bar into an icebreaker. All of the men get keys, the women locks, on a chain to be worn around the wrist or neck. People search for the key and lock that fit together - and when they find a match, they get a raffle ticket for a drawing as well as a new lock or key to continue the game. Christan Marashio, owner of LockandKeyParties.com, got involved after working for a speed dating company. With "Click at a Flick" for the price of a movie ticket, singles get to mingle and enjoy free martinis from Svedka for an hour and a half before the movie begins. Presented by Loews Cineplex and Lavalife. Chris Gonsalves knew he had found a need in the Boston area when 42 people showed up to his first planning meeting for a singles club. Known as funfunfun.org, the club has grown in seven years to reach 80 towns and has about 500 members, from the 20s on up. Members plan activities, from game nights to ski weekends to hikes. You don't have to be single to join the Boston Young Professionals Association, but it does provide some singles events along with its other activities. The association boasts more than 9,000 members, all ages 21-40, who choose from three to five events per week.
