Does anyone else find it strange that the Fourth of July is a big motif in the introduction to "Dandelion Wine" but appears nowhere in any of the stories, is, if I am correct, not even mentioned in the text?

I think Christmas appears about three times in Bradbury's total work, while Halloween is well-represented. Others?

Happy fireballoons fourth of July!

The Fourth of July is also mentioned in 'Fire baloons'. At least in russian translation )
