I grew up on a farm.. wasn't much farming going on but the old barbed wire fence was still in place.
After our years in the Navy Elbert and I moved to... yep, you guessed it... a farm. He bought cows and up went a barbed wire fence. To a lot of people, fences are only to keep critters inside and not out. Not very attractive, but very effective.
Now for something much more attractive.
