The mixer offers social distancing within Nunan’s 10,000 square-foot greenhouse and garden center. Nunan’s began as a family-owned business more than 100 years ago and Steve Flynn maintained the family tradition when he acquired the business in 1985. Chamber members and guests meet Tuesday, April 20, from 4:30-6:30 p.m., at Nunan’s, 269 Central St., Georgetown. It is free for members and $10 for non-members. Register at haverhillchamber.com.
