COVID-19 PROTOCOLS IN PLACE FOR 2022-1 APS RUN CYCLE
CARS mourns the recent loss of Guy Macha. A valued staff member of CARS for 26 years, he will be remembered for his appreciated insight, advice, subtle sense of humor and kindness. Guy will be missed. Our deepest sympathy goes out to his beloved wife Alice, his family and friends.
A memorial service for Guy will be held at 1:30 pm on Saturday, January 29, 2022, at Farkas Funeral Home, 3201 W. Jefferson Street, Joliet IL. Memorial Visitation will be from 10:00 a.m. until time of service. Per Guy’s wishes, cremation rites have been accorded. In lieu of flowers, donations to Lightways Hospice, 250 Waterstone Circle, Joliet, IL 60431 in Guy’s name would be greatly appreciated.
