Thank you guys! The fence is great. I got "scolded" last night during the last training session from the Invisible Fence guy. I was supposed to be using the leashes for 2 or 3 more weeks...but they love to run and well I can't run right now...so I let them run free. They do really well. He was impressed though.
They are liberated! They love not having to drag momma around like dead weight.
The backyard is about 250 feet deep and they use every inch of it. They love hiding in those weeds in the back and sneeking up on eachother and the deer or cats that stroll by. Man we love that yard...no neighbors to look at (YET)...only the corn to gaze at.
