While on Sanibel Island today, I made a return trip to the J N "Ding" Darling National Wildlife Refuge. The 5,200 acre refuge was established in 1976 to protect one of the country's largest undeveloped mangrove ecosystems. The refuge is widely known for its migratory bird populations. It is named for the cartoonist Jay Norwood (he was born in Norwood, Michigan) Darling.
