"Not all types of buildings or vehicles are safe during thunderstorms. Buildings which are NOT SAFE (even if they are "grounded") have exposed openings. These include beach shacks, metal sheds, picnic shelters/pavilions, carports, and baseball dugouts.
Porches are dangerous as well."
See, it says right here that Porches are dangerous
Don't you own a "Porch" ?
