I've made such topics before and they worked, so I hope you're gonna like this one too.
Here are the rules:
- fov=10
- no kenya
- right answer must contain the map name and loc name (however you describe the loc, as long as it's the right one)
- after the question's author points the right answer, the person who answered has 24h to place new screenshot (after that time anyone can setup a new screen)
- if noone guesses the loc within 24 hours anyone can post a new one
- it'd be nice if you gave screens no larger than 640x480, otherwise just provide a link
Here's my teaser:
