“Antiques Roadshow” will air the first of three episodes Monday that were recorded last summer at the Coastal Maine Botanical Garden in Boothbay for the popular PBS show’s 30th season.

The first hour-long episode premieres at 8 p.m. on MainePublic. The second and third hours are scheduled to air Feb. 23 and March 23, according to the show’s website.
About 65 appraisers gathered under tents at the gardens on a drizzling Wednesday in June for the show’s first visit to Maine, and fans wearing raincoats and holding umbrellas waited in line for hours to have their treasured items appraised.
