Way back when I was a curious youth dating a lovely lady who would eventually become my wife, a favorite way to spend time together was to get into the car an drive; follow our nose so to speak. Living in the Chicago area we were within easy driving distance of Lake Michigan, which could have been the Atlantic Ocean for all we could tell on shore. The shoreline heading north of Chicago had some very wealthy residents. It was kind of cool seeing how the other half lived. About an hour up the road in the midst of these Wilmette mansions was the
Bahá'í Temple.
The Bahá'í House of Worship in Wilmette, Illinois. One of eight dedicated temples of the Bahá'í Faith, it is the oldest surviving Bahá'í House of Worship in the world.

It was an amazing sight from the road and we even walked around the outside of the temple. That's all I know about Bahai other than it's kind of a universal religion which promotes being 'at one with the universe.'
Zoroastrianism was founded by the Prophet Zoroaster in ancient Iran approximately 3500 years ago. This predates Islam, the current fad in that part of the world. Every so often, when I read something philosophical, I'd run across a reference to Zoroaster. I can't say that I know much about it, but apparently it's very popular in cultures foreign to me. I don't recall meeting anyone who followed that particular line of belief in the Chicago area. But, the USA is a big place. There could be a whole gang of Zoroastrians somewhere.
