Superior, WI (Northland's Newscenter) - Supporters were busy tonight preparing for Friday's appearance in Superior by Vice President Joe Biden. President Obama's running mate will address supporters at the Superior Middle School.

That's who we are supporting," a sign creator said. Tickets for Vice President Biden's appearance are available at Obama Campaign offices in Superior, Ashland and Duluth. The doors at the Superior Middle School will open to the public at 1:00 tomorrow afternoon. Justin Reis, NNC. jreis@northlandsnewscenter.com
