The Tupper Lake Plein Air Festival is slated to return for the fifth consecutive year next week. The event, which began in 2019, will run from Oct. 1 to 4, with two additional days of art sales at Tupper Arts’ gallery on Oct. 5 and 6. The Adirondack Daily Enterprise reports each day of painting will feature its own unique perk for the artists, according to the event’s website.
