Hello dancers! Our square dance group will be scheduled to meet on October 17, 2021 at 7:00 pm sharp at Green Park. The purpose of the gathering is to get together and discuss which square dances we will be learning in the upcoming days, when we will be conducting the lessons, and matters such as dress code. We hope you will all be able to attend on time. We hope that those dancers who can attend will sign up in the group first. Thank you!
