Wayland Patch 8/16/11: Party Planning Continues for the 375th Anniversary Committee – Wayland, MA Patch. Planning a party worthy of a 375th anniversary requires more than a couple of phone calls and an order for balloons. It requires more than two years of brainstorming, fundraising, negotiating and organization to pull off a yearlong celebration designed to entertain and educate a town of 13,000 people. In 2013, Wayland will celebrate its 375th anniversary, and the 375th Anniversary Commemoration Committee is already hard at work making sure the celebration is a success. At Monday night’s committee meeting, the team spent much of the evening hearing from Allison Tobia and Deborah Seidman who are working specifically on a kid-friendly, family fun day that will serve as the extravaganza of the yearlong anniversary celebration.
