A number of photo club members are aware of the work, including videography, that Thomas Walsh has done to bring some attention to the very extensive, yet rarely mentioned, abuse of children by nuns. On Tuesday, April 5, Thomas will give a presentation on the subject from 7 to 9 p.m. at Tina Davis Studio, 947 Kimbark St., Longmont. The meeting will take place under the auspices of LightOn Creatives for Community, a Longmont based group of creatives actively involved in further expanding the already burgeoning Longmont art scene.
