There's a place I call Evil Gorge, sandwiched between The Evil Mansion and the Enchanter's Tower. To the South is Disco and to the north is the glass mountain. It's such a cool (natural) place but has been ruined by Endermen over the years. It's also ruined by lag thanks to the up-draft of the melon farm. I decided to take the plunge during my lighting mission to tidy it up.
You can see some grass still propagating. The glass mountain is rather sad with the farms pushing through it. I'm tempted to take it down and give the farms some medieval shells.
