Winterized

While we're away this winter the hot tub will be drained and antifreeze put in it's many ports and tubes.   The other thing needed is to protect it from ice and snow.  The solution shown is what we came up with.  There's a big exercise ball which is covered by a large plastic sheet held in place by nylon netting.
The netting is anchored down with bags of water.  
    I hope its enough but won't know for sure until we get back.
