Pot of Gold?

Today, at or about 5 pm eastern, I was driving through a microburst. As I entered Weston, MA, the storm intensified and concurrently bright sunshine burst behind me. This confluence yielded a rainbow - one end of which was right in front of me, and I drove right through it - colors all around the car. This is actually the 2nd time I've had this experience - the first one being on a Nova Scotia camping trip with my son, Jon. Unfortunately, no pot of gold, in either case. But it was still really cool.
