Winter flying can be a pain, I have my own plane and I need to show up at the airport an hour and a half before I fly to preheat the engine. Often during that time I'm out shovelling snow infront of my hangar. I also take the battery home with me every day. Then after I finally start the engine while I'm waiting for it to warm up I use my engine preheater to warm the cabin and avionics. I miss summer already!
