It can be risky but the planning helps mitigate that which is why it all has to be planned out so well.
As for snakes, yeah I'm not a fan of snakes; they give me the bloody creeps. But, I've lived with th m my whole life (I'm from the country, not a city) and know how to minimise that particular threat. I also have the right emergency equipment which I've written about here and there.
If you never hear from me again after I leave for my trip you'll know I fucken died. 🥴
Oh my God, don't even say that as a joke! You'll come back safe and sound and with more experience, that's what I'm going to think.
