After years of being grounded due to the recession, the old-fashioned paddlewheeler riverboats are back along the Mississippi!  The new American Queen will make a stop in downtown Cape today from noon until 5 PM.  About 400 people are expected to come ashore and spend the day touring the downtown sites and shopping.  Cape convention and visitors bureau spokeswoman Stacy Dohogne-Lane tells KZIM KSIM they’re excited to welcome these tourists back to town.  The American Queen guests are on a 7-day voyage from Memphis to Saint Louis.  They already made stops in New Madrid and Paducah and are on their way to the 4^th of July celebration by the Arch Wednesday.  They have paid anywhere from 2-to-6-thouands-dollars for the cruise.  The American Queen will dock again in Cape September 12^th and November 13^th.  The smaller Queen of the Mississippi boat will be in Cape August 30^th and November 5^th.
