Summer ain’t done yet. The past few days have given us a cooler preview of autumn, but the heat returns this weekend, with temperatures expected to be in the 80s and mostly sunny skies.

This weekend offers music and learning. Take the kids to learn about Mexican butterflies. Check out the concert and a screening of “Goonies.” Meet kids with war stories from Ukraine.
