Go to Home Depot & Get yourself some 3/8" or 1/2" Rebar,cut it yourself with a Sawzall or Carbide bladed Circular saw,or Pay a bit more for the 1' pcs.,located in the Brick/Mortar section,they are around $2.00 ea.,Can't go wrong with the Rebar for stakes,they have ridges formed into them for added no-slip ability,you will have to beat them into next week to extract them, but they seem to like it anyways,Perfect for Car camping,Good Luck!
