A few days ago, we received an electronic note from my Dad, famously known as the boys' Granpa Bill.  The noted said:

Not often, but periodically I see something that you may enjoy.  I generally table my decision for a time considering all the elements.  As is my nature, showering gifts to others is something I am not known for, and then again I like to draw the curtain open and let the whimsy fly.  Also, as surprises go, I don't like to let out any hints so I won't at this time either.

We were puzzled but patient and yesterday we were rewarded for our waiting with this:

{I had to include a picture of our favorite element, Uranium, as that is what really keeps the food on the table around here.}

Thanks, Dad!
