Cars have made way for flatspins, can-cans and supermans which will be performed tomorrow night before a crowd expected to number 5000.
While the ramps and other features in last year's event were nothing to look down on, course co-designer Kelly McGarry said features had been enlarged for 2013.
''We've made everything a bit bigger.''
A new feature includes the quarter pipe at the end of the course, pictured being built by volunteer Emmerson Wilken.
