George, what a simple but brilliant idea! A hat that has an umbrella attached, this would be an incredibly popular idea I think, because who really wants to have to hold their umbrella up with their hand for a long time? This would make me more likely to go out for walks in the rain and generally just be outside more when the weather is bad, which is a good thing because you don't want to be hemmed in by the bad weather. Great work, George, keep on inventing!
