This is true. Personally I feel it's much better than putting the dog out on a chain like some folks do. The poor things start running after another dog, reach the end of the chain, and get choked. With invisible fence, I've never really had issues with dogs roaming into my yard too much because my dog is a dominant border collie mix and chases any that enter out of the yard. She stays in the yard and keeps the others out. In fact, the neighbor whose dog is always roaming free just broke down and got invisible fence installed because the neighbors got together and had a talk to him.
By the way WMR, how's school treating you?
