Grab the kids, limber up the digits and head to the CT Convention Center next December* for LEGO Kidsfest. Activities include a model museum, master builder academy, marketplace, games and perhaps coolest of all (we think) race ramps. Perhaps the only thing lacking is a contest to see who can guess how many total LEGO pieces in all will be present. (12 million? 15 million? Anybody? I'm terrible at this sort of thing.) Two four-and-a-half hour sessions to choose from each day (except Friday, when there's only one).
Dec. 6-8, 2013, $18-$20, Connecticut Convention Center, 100 Columbus Blvd., Hartford, (860) 953-4500, ctconventions.com.
*Correction: an earlier version of this article incorrectly stated that Legofest was taking place in Hartford in 2012. We apologize for any inconvenience this has caused.
