Alternate US Holidays calendar

I've been annoyed with the obscure holidays in the default US Holidays cal. I just want the major ones that most Americans care about. Religious holidays of tiny American minorities deserve their own calendars. A Hindu calendar would be great to have available separately.

Here's one that I found that seems to work well. Does anyone know of any other good repositories of importable calendars?
