Gawd, hadn't really thought about snakes at night. Though I do tread carefully at any time, as we have seen browns. Thankfully our main obsys are set up in the goat field (thinking of naming the overall array the GOAT, just need the words that make up the acronym!). And the ultimate irony is that, the obsys are so well built that they'll be here long after us, and in the end, most likely be used as ...goat sheds
Spiders are a pain too, just evicted one from my allsky cam and wiped some surface spray on it (not the spider ..)
I always say, nature tries to win. The trees always win. Think about it...
