1. Consult your doctor before performing this insane activity. He may want to do a psychological exam, that’s ok, you’ll pass.
2. Before leaving the warm comfort of your home make sure to bring your GoPro because you are going to want proof to show your friends that you are, indeed, that crazy.
3. Leave your car running, with the heat on high. Sure, this might waste gas but it won’t be running idle for long, trust me!
