A pdf version of our current calendar can be found here. Messages left to register for fee-based programs do not guarantee a reserved spot. Reservations made over the phone for fee-based programs will only be accepted with a payment. If you prefer to register by mail, please complete a registration form and submit it along with your payment. Please note: Our online calendar only displays programs two months in advance of the current month. If you are looking for a program more than two months out, please return to register for that program at a later date or call to inquire. Thank you.
