Hmmm yes, I've had things like this before. Mainly it's when I see a sunset, and I think of an african sunset, or the sunrise on tlk, the red glow in the sky, that sort of thing, natures wonder.
Then also, there's one particular type of Eucalytpus tree that has a very similar shape to the acacia trees of africa, and there's one road in particular that has a lot of them, and so every time Im going down that road, I think of africa and being out there, on the savannah.
