Thousands of revelers will spend Fat Tuesday partying in Mobile and New Orleans. New Orleans is better known as a Mardi Gras destination. But Alabama's port city also is alive with parades, a ball and neighborhood festivities to mark the coming of the season of Lent. The first of four parades through downtown Mobile begins at mid-morning. Parades also are planned for Tuesday in Gulf Shores and Orange Beach. More than 50 groups put on parades and balls on the Alabama Coast during the Carnival season.
