Portable electric fences?

Anybody know anything 'bout portable electric fences?

I'm interested in the kind that you set up around your camp when back packing. You also use them when using livestock to pack in your stuff...you put them around your beasts to keep them in.

I think that they are powered by D cells.

Go to Big R or some other farm and ranch supply store. Get you a little fence charger. Most chargers run off car battery. For fence use the wide nylon fencing string. It comes from binder string size clear up to 1 and 1/2 inch wide. Get you a few little rebar posts or 5 foot T-posts and some insulators and you are in business.
Tip IF you are putting livestock behind electric fence make sure they know what that fence is before you take them up into the hills. If some of your animals are aggressive, make your pen big enough that everybody has enough personnel space.
