bear creek' s beginner park is a joke. 2 boxes that are usually harder than the gap ons, on a slope no longer than my suburban backyard.
terrain run at blue is uber fun. you must have hit shawnee on an off day, its always good there when i go. mountain creek actually has 2 peaks dedicated to parks, but im not sure about their beginner stuff.
big boulder has freedom park, which has a few flat boxes. but its always crowded and full of cocky ass fools. blue is your best bet.
