This weekend thousands will be attending outdoor festivals of all kinds across the St. Louis region. There are lots of choices…  The Greater STL Hispanic Festival runs thru Sunday at Soulard Park. On Saturday its the Great Forest Park Balloon Race.  The Harvest Fest in Augusta features a parade and pie contest, and at the STL Renaissance Festival in Wentzville you’ll experience a re-creation of a a 16th century French Village. And on the Carney show, Dan Warner previewed Saturdays Old Webster Jazz and Blues Festival in downtowAlton riverfront, and then there’s the 17th annual Apple Fest at Pere Marquette, where you can take part in the pumpkin roll, or the apple pie walk, which they bill as similar to a cake walk..but better.
