What's at the end of a rainbow?

My house. Really, it is, or it was anyhow. This evening it rained and we saw a beautiful rainbow and it came down right in front of our house on the road. I've never seen a rainbow so close in proximity to me. I should have gone outside to see if I could hop on it and travel to the land of Rainbow Brite but I'm still feeling like crap so I stayed in the house.
