Park Spirit is sponsoring three Saturdays of free ice skating at Elm Park. They are Saturday, February 5, 12, and 19 from 10am-2pm (though the last two times appear to be incorrect on FB). From their Facebook page:
Bring your own skates. We’ll supply the hot chocolate and warm fire.
Skating Day will take place pending “safe ice” clearance from the City of Worcester.
Crompton Park Ice Skating Rink (at the tennis courts at Crompton Park) — Open daily as weather permits from 10am-5pm. There will be special Friday evenings on January 28 from 5-8pm and February 11 from 5-8pm. Call 508-755-1228 to confirm weather and ice conditions.
Free used skates available if they have a pair that fits you (M-F noon-2pm at Pernet Family Health Service).
