Snakes hey. I wonder if snakes have a natural predator they instantly recognise and steer clear of? If you kept a few birds of prey around the garden this should do the trick. Or even cats? We have snakes here but they are not dangerous, so i've never looked into this, but there is usually a simple solution.
That was indeed a yellow pear tomato, grown exclusively because my daughter refuses to eat red ones! Children are funny like that. They taste better this year than ever before, thanks i would say exclusively to the electroculture.
All the best to you and many thanks for the message.
