I guessed it might be a garter snake, but really, 'yellow with markings' - that's all she told me. When she eventually stopped and looked back up the hill, her partner was there calmly photographing said reptile so when she brings the photos in, we'll be able to see.

As for dangerous critters - given the size and number of her mosquito bites, I think my manager would disagree.

Thanks chaps.
