Rain Barrel Footings & An Empty Wine Rack

These are the small footings for the rain barrel that stands alone on the opposite corner on the back of the house:

 They are 8" square, and 4" tall.  They will support a small steel table upon which the rain barrel will sit.  They will be embedded into one large concrete pad, as opposed to 4 small ones.

I'm a little bit twitchy these days about my rain barrels.  Two of the 5 had to be emptied so that Vic could move them.  A third one, when our weather got cold, the hose came loose and the whole thing drained.  I knew the connection was bad, but had been procrastinating repairing it, so I suppose I am to blame for that one.  But I am down from about 275 gallons of water to 110.... for some reason that's akin to not having enough good books in the house to read, or having a wine rack that is less than full...
