The sixth annual Gardens Aglow event, put on by Coastal Maine Botanical Gardens, is a drive-through experience this year to maintain social distancing due to the pandemic.

Tickets must be reserved in advance this year, for safety reasons. A sign instructs drivers on the drive-through tour, which is about a mile long and takes 20 to 30 minutes.

A lighted tunnel awaits drivers. The tunnel is decorated with about 40,000 lights.
