Hey, Frank.
You're one dedicated soaker! :-?
I love tubbing - and I love storm watching (especially out over Lake Huron - lightning strikes over water are spectacular!) but these are two pastimes that are best experienced separately.
Now by all means, if you want to tempt fate go ahead! The odds are in your favour.
Hell, wear an aluminum foil hat and give the clouds the finger if you're feeling particularly brave and foolish. The local papers always need front page material...
