Parts of the storm-ravaged U.S. East Coast are trying to get back to business Wednesday.
New York City Mayor Michael Bloomberg was at the New York Stock Exchange on Wall Street to ring the opening bell. It is the first time traders have returned to work since Hurricane Sandy walloped the region, flooding parts of the city's famed subway system.
Two of New York's three airports are beginning limited services, though LaGuardia Airport remains closed because of flood damage.
Airports, rail service, and local public transit in other cities along the Eastern Seaboard are also resuming services.
But there are other signs that many areas still have a long way to go.

Later Wednesday, U.S. President Barack Obama visited the storm-battered state, where many are calling Sandy one of the worst natural disasters ever to hit the region.
Obama and New Jersey Governor Chris Christie viewed the damage together and thanked emergency workers for their efforts. On Tuesday, Christie, a Republican normally at odds with the Democratic president, praised the Obama administration for what he said has been an "outstanding" response to the destructive storm.
The president has declared "major disasters" in New York and New Jersey, freeing federal funds aimed at offsetting billions of dollars in East Coast property damage.

With the presidential election now less than a week away, Republican presidential challenger, former Massachusetts Governor Mitt Romney, was back on the campaign trail in Tampa, Florida on Wednesday. But he asked supporters do what they can to help the relief efforts.
"People are doing that all over America, gathering their support in any way they can to help the people who have been subjected to this tragedy," said Romney. "And so, please, if you have an extra dollar or two send them along and keep the people who have been in harm's way, who have been damaged either personally or through their property, keep them in your thoughts and prayers. We love all of our fellow citizens. We come together at times like this."
The storm's impact has even caught the attention of the Vatican.
On Wednesday, Pope Benedict spoke about the disaster during prayers.
"Conscious of the devastation caused by the hurricane which recently struck the East Coast of the United States of America, I offer my prayers for the victims and I express my solidarity with all those engaged in the work of rebuilding," said Benedict.
Sandy has killed at least 45 people in North America. The storm hit the New Jersey shore late Monday, causing massive flooding, raging fires and power outages that crippled the New York metropolitan area.
