I have seen as many snakes orienteering in Sweden as I have in Aus , contrary to common theory. If it was the one that looks like a MTB tyre apparently it was a European Viper and to be avoided especially by Kiwis.
Yep, that's the one! Luckily the habitat of most kiwis is a safe 1800km away, so easy to avoid! ;)
It's just the very lost ones that end up withing biting range!
