Katie Couric's Notebook: Capped Well

What was almost unimaginable following failure after failure has actually happened...the well has been capped.

It's a temporary move and we shouldn't be breathing a sigh of relief just yet. After all, as we've learned, anything can happen. The relief wells are the only permanent solution, and residents along the gulf coast have to deal with more than a 150 million gallons of oil still menacing their shoreline and fragile wetlands. The spill is also destroying the livelihoods of people who depend on the fishing and tourism industries to support their families.

It seems fixing this problem was harder than putting a man on the moon. Now we need to do everything in our power to ensure those people get the help they need, and this never happens again.

That's a page from my notebook.
