Wow, that's good thinking of the nephew! Most people would sit there and stare at it happening instead of reacting.
It is the same down here too as far as down fence. When we rented this house, the neighbor leased the pasture for his farmer cows...he never really fixed the fences, no need when everytime you walk out on the front step your cows start bawling and run up to you. Anyhow I did some fence fixing before I turned our horses out and that is what I found, old fence everywhere! So I spent some time trying to clean that up...especially since Stilts is the most accident prone living thing I have ever had contact with in my entire life. The others I couldn't kill if I tried.
I don't know how you guys deal with it...the fences, the briars, the vines and them crazy poison sticker things..really???lol
I DON'T LEAD 'EM AND FEED 'EM, I RIDE 'EM AND SLIDE 'EM.
