Tarp Stay!

Here at dansbois, we sometimes have to cover things from the snow/rain.  This time we had to cover a big round bale of hay.  Jerry came up with this idea.  A 2 liter bottle.  The cover is pierced to accomodate a hook.  Then, a washer and a nut are placed both inside and outside the cover which is then screwed back onto the bottle.
Usually I would have used sand in the bottle for weight.  When I needed it the sand/ground was already frozen so I just used water which once frozen made the bottle heavy enough to hold the tarp down when it is windy.  It is easy to remove a few of the bottles, get what is needed underneath and then replace the tarp and the bottles.  Works great!
