There is a net between two specific areas, one with great steep slope and the other a level slope. One man shows off by running up the slope, then jumping over the net with a parkour move and then getting to the other side. Doing the stunt myself, I find that it is harder than I expect. However, after a few times I realize it can be even harder if the net faces upwards, preventing easy movement to leap across the net. The man admits that even he may have trouble as I get stopped a few times before I finally manage to make it across in one try.
