Or rather, snake in the netting. This grass snake had got itself tangled up and I had to cut it free while the plot holder, Brian, held it still. We weren't sure whether it was a grass snake or an adder until I got home and googled it, so it was a bit scary. Fortunately I quite like snakes, if it had been a spider I would have run a mile.
Anyway, no harm done to the snake and it was set free at the top of the plot, by the hedge. Good luck to it, netting can be lethal to wildlife, from now on I'm going to make sure all mine is stowed away in my tool box or bin when not in use.
