The USA in 4D

Every day was a new puzzle.  Every. Single. Day.  Liam would wake up and already have a plan as to what we were going to do, as if he laid in bed and dreamt of our puzzle play date.  It was obvious he had an agenda for us each day and he wouldn't let me forget his ideas for one second.  This was one of the puzzles that he got for Christmas.  It's a pretty cool puzzle, I think.  Tons and tons of pieces I might add.  In fact, there were so many, we both gave it a rest.  I love the landmarks you can stick in the puzzle.  What a neat idea!  We're still trying to figure out which landmark goes where.  They all start to look alike after awhile.

We have yet to finish this puzzle.  You have to add regular puzzle pieces to the outside of the US.  There are hundreds.  Gah!
