I got to within ten feet of the end of the rainbow driving to a Tacoma Rainiers game one time. It was right behind the car in the lane just to the left of me. He was a little ahead of me and the rainbow end was chasing after him. Maybe he was a leprechaun with a pot of gold in his trunk. Then there was the rainbow that ended in the dump outside of Flagstaff that one day. Never found the pot with or without a leprechaun.
