The Louisiana Purchase stretched from the Mississippi River to the beginning of the Rocky Mountains. Official boundaries were not determined, except that the eastern border ran from the source of the Mississippi River north to the 31 degrees north.
Cooled (or air conditioned) seats work by confining cooled air directly in the seat where the passenger is seated. Multiple fans are put within the seat to provide air circulation. The air from the fans blows through a diffusion layer to spread the cool air throughout the seating material, cooling the whole surface.
Check your car seatâs instruction manual or look at the information label on the side of the car seat to find out its weight limit. Most convertible seats (those which can go both rear-facing and forward-facing) have rear-facing weight limits of 35 or 40 pounds, although some newer models go up to 45 or 50 pounds.
