Abstract: A vehicle-attachable ice fishing shelter comprises a shelter body formed from flexible sheet material including a vertical wall panel defining three sides of the shelter and a generally horizontal top panel adjoining the wall panel. The shelter has an opening on one side. Top and side edges of the opening are secured during use to a road vehicle, e.g., a car, truck, SUV, etc., above a door of the vehicle and along the front and rear edges of the door opening so as to position the shelter adjacent to a door of the vehicle for enabling a fisherman sitting in the vehicle with the door open or closed to fish from the vehicle through an ice hole that is located within the shelter. The vehicle heater provides a draft of inflation air for heating, expanding and supporting the shelter.
