Calithumpian is Thamesford's May long weekend community-wide celebration! With a long history, Calithumpian is rooted in tradition, and brings back a lot of great memories for many people who grew up in the area. As we move forwards, like us, it continues to grow and evolve! For those who have been and those who have not, everyone is welcome to come out and enjoy the many activities and festivities of Cali!
