One-time Mercury News reporter and bay advocate Gil Bailey’s ashes were scattered at the Don Edwards San Francisco Bay National Wildlife Refuge in Fremont the other day. Bailey wrote a series of articles in the late ‘60s on the need to save San Francisco Bay. Among his readers was Rep. Don Edwards, who later hired him as an aide before introducing legislation in 1972 to create the refuge. Bailey died in April at his home in Washington state at age 78. Today the Merc’s Scott Herhold devotes a column to Bailey and his legacy.
