I have been kayaking in Prince William sound where the tanker crashed and spilled. This was in 1997. As of then Exxon had publicly declared that all the oil had been cleaned up at great cost to them. There was no more remaining oil spilled. I spent 30 days hopping from island to island, camping out, and all one had to do on a number of islands was flip over a few rocks and there was oil underneath. This oil was from the Valdez, and was still not cleaned up. This should come as no surprise to anyone.
The resilient wildlife had made an incredible comeback and i had a dreamlike experience. Yet it was sad even then that Exxon was not being held accountable.
