Today is Presidents Day, or the federal observance of Washington's Birthday which is a national holiday. Whatever you call today, it means most local, state and federal government offices and financial institutions are closed, there is no mail delivery and post offices are closed. Local courts are also closed, as are most schools.
Trash delivery though will go on as usual in most places, and most retail businesses are open today. Some libraries are closed, including Hayner Public Library in Alton, so called ahead to be sure. Financial markets are also closed today.
