10-foot concrete ramp with a bowl on one side found in the outskirts of Mui Ne in Vietnam. Reddit user @Aawkwardhandshake posted that he and friends found it on this thread.
The exact location is not entirely known but he left instructions to find it as follows:
I know that if you find the main road leading into the town, that's the one the skate shop is on. I guarantee if you find it, the guys would show you the ramp- and if they're closed go to the pharmacy right next door!
