August 22, 2024. Rain for Shine. Please join us for an ALL NEW offering from MTWFA! The 2024 MTWFA Field Day will seem familiar as we will be returning to the Upland Sportsman Club in Plympton, MA. Those of you that attended the South East Tree Wardens event at this location will have questions: Will there be local exhibitors? YES! Will there be a chicken bake? YES! Will it be priced so that I can afford to bring my whole crew? YES! But wait there’s more… this re-vamped event will also provide CEUs focused on safety in arboriculture. Registration NOW OPEN. Attendee Registration. Exhibitor Registration.
