I can't remember if it was after Ash Wednesday or Good Friday (or both), but my parents would eat an Italian sandwich after mid-night. The "Holiday" didn't have a name, but I guess you could call it Fat Thursday or Fat Saturday? Might be more of a tradition than a holiday.
Driving home from work one day it was raining and I was on a toll road, so not much on either side of the road. There was a rainbow in front of me in the sky. As I got closer I saw the bow dip onto the land. As I got even closer it started going further over the land until it seemed to wrap under my car. It was like I was driving though the rainbow. Only experienced this once. I think it was the water hose set up on a grander scale.
This does look like a good way to spend a Saturday.
