Garage heat

Run Natural Gas to your garage. Insulate and install some type of walls and ceiling, sheet rock, OSB, or even steel siding. install a small unit heater 30-50k unit. Your life will forever be changed. Leave it 45-50 degrees when you are not using it and 60 or so when you are out there. You will be very happy and productive, plus your tools, cars, parts etc. will never rust again. Run a larger power line out there for a sub panel while you are digging. Then you can get an air compressor and maybe even a window unit a/c. it always seems like we need to work in our shops when it is bitter cold or hot and humid. Unit heaters and window A/C units are pretty inexpensive and will make you very comfortable.
Good idea. I already ran a Romex power line and installed a sub panel but have not hooked it up (I'll need a licensed electrician for that). Summertime would be the right time to have a NG line run out there. I will check into pricing.
