JACKSON, Wyo. — Wolves weren’t the only animals howling at the moon last night.

A new Facebook group called HOWL for WYOMING is encouraging Wyomingites to “support our medical teams, essential services, and individuals” through song. Wolf song, specifically.

Similar groups have popped up across the nation. The idea is simple: every night at 8 p.m., “head outside your home and HOWL or CHEER for our healthcare workers,” the Facebook group says.

The group encourages participants to take photos and videos of their participation to share and encourage others.

The group is public and all are welcome to join.
