WILTON -- Children crawled through "CoCo," a 40-foot long replica of a human colon, on Tuesday at the WIlton Branch of the Saratoga Regional YMCA.

Colossal Colon was created by Molly McMaster Morgoslepov, a colorectal cancer survivor and the group health and wellness director at the Wilton YMCA. She was diagnosed at age 23, and commissioned Adirondack Studios in Argyle to build the colon as a way of reminding people young people can get colon cancer too. The structure also is in memory of a 27-year-old friend who died from the disease.
