Garden 'Lids'

I took the time on Saturday, with a little help from my friend Jerome, to build two 'lids' - for lack of a better term - for the garden.  Just something to cover an area where Kate plants things so the squirrels don't dig it all up.  In this picture is the bottom of the west garden.  There is garlic coming up that was planted last fall and above that, covered by the 'lid', is more garlic that she planted on Saturday.  I thought I may have to screw it down, but the squirrels have not moved it at all.  They can get underneath if they really want to, but so far it seems they don't want to, which is very good.
