I found a roll of KodaColor 200 which expired in 1988 tucked away in my darkroom frig, not frozen, just kept cold. I shot it at 100 and took it to Target, colors seem a little muted, but not bad. I would shoot the C 41 and take it either Target or Walmart for processing. At one time there were a couple of labs that process E 4 and C 22, but were expensive, Rocky Mountain Labs come to mind.
