Watertown residents seek glimpse of first lady

Excitement is growing in Watertown, where first lady Michelle Obama is expected to appear Thursday afternoon.

A few residents are sitting in lawn chairs along the street leading to Watertown High School, where Mrs. Obama plans to launch a new campaign to help encourage people to drink more water. Security at the school is tight.

The campaign run by the nonpartisan nonprofit Partnership for a Healthier America is being backed by leaders from industry, entertainment and government.

The White House says Obama chose Watertown as the place to launch the effort because the goal is to make every town a water town.
