i have seen some poisonous snakes but not really big ones. I’ve also been bitten by spider that was weirdly cool, (see I grew up where there was lots and lots of house spiders, never thought I would ever say I been bitten by spider) it wasn’t poisonous, pain was really weak, but then again I was comparing it to a scorpion sting, that sent me to hospital.
The only moment I’ve felt scared was one day I was driving just out of town, wasn’t even that early probably around 7am, there was a family of kangaroos on the road, and they had huge ones too bigger than my car, they intimidated me for a few minutes, stop when I stop and hop/run faster when I move basically chasing the car, eventually they went their way. I love the little joeys and we often hang around them by the river but the big adults can be quite aggressive.
