A big thank you to the INTERSTATE employees who volunteered at the Touch-A-Truck events in Greenwich in Westport! Getting to connect with local families is always one of our annual highlights, and we couldn't do it without the dedication and work of the INTERSTATE family. They pack the flat bed with materials, get the forklift ready, and hand out custom tie-dye shirts and water bottles to attendees. Fairfield County is a wonderful community, and we're so lucky we get to be a part of it.
