Watch it, if you aren't careful, the pro may cut the asphalt on your driveway to drop wire if you don't specifically say "no".
I'm not sure I understand this. I have an electric fence in Mass and it does go across the driveway. If you don't the dog will just walk out. The (small) cut was filled and never been an issue you don't even know it was done. The system is about 10 years old now. Do have to remember to take the collar off though if your dog goes in the car with you........oops........
