Not too late!
Bill is going away for the weekend, so probably won't work on it again until next Tues. By then, we can take all of the photos that have come in, and see what is needed to complete what we already have.
Of course, the good thing about PP is that it is never REALLY too late - even after I give the talk the first time, I will continue to add and subtract, and move things around, to try to perfect it for the next talk.
So keep the photos coming! Thanks!
