Looking Back At The Gulf Oil Spill, One Year Later

Today marks the one year anniversary of the Deepwater Horizon oil rig explosion, and the beginning of the worst oil spill in U.S. history.

Eleven men died in the blast, and more than 200 million gallons of crude gushed into the Gulf of Mexico.  After the BP oil spill, fishermen lost their livelihoods and tourists vanished.  But a year later, a Pensacola Beach restaurant owner says  business is  improving.

"We've gotten a lot of locals and a lot of spring breakers. We're probably up 15 or 20%," Michael Pinzone said.

Experts say it could be years before the full effect on the environment is known.
