How to: Air field

This is for pro students only, if you're not one of those please skip this part.To get into the airfield you can go to the trampoline and walk around the cages but it's not impressive as the fast way.For the fast way, walk to tants, pick some random tant, run and jump and then turn around 180° and walk backwards.It's very hard but don't give up. When you succeed walk on the wall and jump above the fance.
