I have read on these boards that it helps beat the summer heat to buy those fans that spray water on you. I so far have seen one of them in the store. Are there many out there to choose from and which one is the best. The one I saw (in Kmart) seems bigger than I expected. I can't imagine having to "hold" the other family members fans when they aren't using them, especially with water in them. Do you think one shared with everyone works?
