The gathering was the first of its kind, at least in years.

Crag Rats celebrated 90 years as an organization serving the community, with an open house at Crag Rat Hut on Oct. 30. The fire roaring within the huge, welcoming hearth was as much symbolic as a need for a heat source on a temperate afternoon as Crag Rats opened their doors and served cake and punch to about 100 people, including numerous Crag Rat alumni, many in the Crag Rats’ distinctive black-and-white check vests, shirts or jackets.
