The electric wire at my barn is basically invisable! All the kids get shocked and we know this can't continue,but the cost of new installed electric wire is just not in the mix right now. What is an alternate option instead of SHOCK SHOCK SHOCK!
We use what firelight was talking about at my barn. It is extemely easy to instal (me and one other person put up 2 acreas of fence in around 30 mins) and if something happens it is really easy to fix. I totally recomend it, and it look really nice.
