An Active Imagination

I have an active imagination. It's also about as scattered as the continents. Yesterday, I went off. I saw a ditch in the side of the road, and I thought about how water and wind erode the land. I thought about how much water it would take to turn that ditch into a river, and when that might happen. I thought about the flooding that seems to be happening a lot these years in the mid-west, and I thought about how new rivers might form out there because of the erosion. I thought about how map makers will have to update maps due to things like this.

I don't know why I think these things. My brain just goes, and I can't stop it.

So where do you think new rivers might show up some day? Which mountains do you think will erode first?
