The older I get, the less enthusiastic I am about shoveling snow, so I'd like to get some comments, information, literature, etc. about heated driveways. What little I have seen leaves me with the impression that they are very expensive i.e. $12.00 to $20.00 per square foot...so a 30' X 70' area would cost $25,000 to $42,000 and that's a lot of snow blowers. Is there a less expensive way to get this done?
