First Selectwoman, Old Lyme. Re: Midsummer Festival is this weekend - with a free concert on the lawn of the Florence Griswold Museum on Friday evening, a 5K Run/Walk to support the Timothy Buckley Foundation on Saturday morning, and lots and lots of stuff going on all day Saturday from the Bee and Thistle (an antique car show) to the Phoebe Griffin Noyes Library. Lyme Street will be a buzz of activities.
