We cloned the following two Mason notices from another site and both appear on the town calendar:
Saturday April 12, 2014, 10 am to 1 pm — Rabies Clinic at Mann House ($15 per vacc)
Saturday April 12, 2014, 10 AM at gazebo at center of town: The Mason Recreation Committee is sponsoring the annual Easter Egg Hunt. Bring your own basket.
Not sure the two are related unless your dog is good at sniffing eggs. You can find more information about the Easter Egg Hunt at the town web site.
