What the hell am I gonna do with a 2.6m (that's about 8'5"!) snakeskin?? I have no idea, and it seems like a waste to just throw it out.
Would you be freaked out finding out that a snake that big was slithering through your yard at some point? I've never seen snakes in my yard, though my flatmate has seen small ones (about 20cm). We have a creek right behind our house, so it doesn't surprise me. Seeing it alive might have given me a bit of a start, though.
