I wish people would stop fucking making up theories because they don't understand what they are looking at. The tennis court is flat. The 3d mapping software is trying to use the ground photo as a texture on an elevation map and doing a poor job. Probably the data set is too limited. The berm around the tennis course is wind abatement. Islands are windy. There are soooo many other interesting things about the island. Fuck the tennis court.
Says the fucking guy reading and posting on the forum… LOL.
