Sweet Willie,
I saw your question on a different thread about when is the best time to go to Venice and not get crowded out by tourists.
Actually, it is at the very moment you will be having your Whirlyball FT Do.
We will be in the middle of our big Venice Meet on that day (actually, most people will be arriving on the 18th or 19th and leaving around the 23rd or 24th.)
If the Chicago Do doesn't work out, you are very welcome to join us. In fact, I can see where playing Whirlyball from gondolas on the Grand Canal could start a whole new international craze!
