The Eastham Public Library is hosting a “Virtual Lego Challenge Countdown” on Friday, February 19th, at 11 a.m. to noon. There will be timed building challenges with opportunities to share your work. Use whatever Lego blocks you have sitting at home, or email [email protected] for a starter kit. Stick around until 1 p.m. and there will be a virtual tour of Boston’s Black Heritage Trail led by Park Ranger Amelia Benstead. Registration is free at easthamlibrary.org.
