Those temp garages are set-up around October 15 and come down on May 15 every year. They are very common here and are great to have in the winter months. We have to brush off the top after every snow storm, tapping with a broom from the inside. They resist the wind, rain etc. It takes about 1 hour to set-up, and they cost about $350, mine is about 5 Winters old and still look great!
