These guys actually climbed over the fence to get into the Thrasher Park at the City of San Leandro.
The park was probably not opened and it did not look like it was in maintenance so it was probably a park that was no longer opened to public.
They were doing this illegal to film this skate videoclip at this Thrasher Skatepark.
They tested the skatepark to experience this out of bound skatepark.
This skatepark was really not a good place for skateboarding and the ground was not smooth enough.
The online review of this skatepark was also really bad.
It was still a nice fun adventure for these guys.
