Bing always has great patriotic backgrounds for national holidays.
Bing it is.
I reluctantly stuck with google because you can narrow the search and it was real good at catching my spelling errors -- though it was extremely irritating when I spell it right and google substitutes (adds) what it thinks I really meant.
A cursory look at Bing shows similar features -- though I hope it does not add strings of characters for what it thinks I meant.
I have not found yet how Bing will let me narrow a search to a year or more in the past not including the current year.
