Puzzle exchange

Well today was the day. As always it was a blast. 6 1/2 hours of talking about the object of toys. If I had a $$ for each time I heard someone tell me the object was easy.....

I can't wait to YouTube each and every one. I've managed to solve one thus far.
My exchange assistant solved 2 in that short time.
We are now listening to Jerry give a talk on the history of IPP. Later this evening is the banquet. In the mean time, here are the exchange puzzles.
And of course I'll later report on that!
