Yes, it seems like a bumper crop of snakes this year. I'm in Bastrop County in central Texas and I am averaging seeing 1 snake *a day* on my ranch. And that's not counting the snakeskins that I find here and there. Fortunately all nonvenomous and mostly rat snakes, but have also seen hognose...
I know what it is like to have to leave your animal family. I hope everything will be all right while you are gone. Will there be anyone checking in on them for you?
