i have to agree with x on this one. the shoes are like sturdy winter shoes that go on like sandals. great for getting the mail starting your car etc. kerosene torpedo heater >propane torpedo heater. mine lasts for weeks on one 5 gallon can. last night i fired up my kero torpedo while i cleaned the driveway only to walk back in and have my garage at 87 degrees. (my garage is fully insulated, drywalled, trimmedout, insulated doors, and pella windows) although i have to admit i have been thinking about a small woodstove myself now that the vw is leaving.
