I’ve recently had the opportunity to take several car trips from the North to the South and back and forth, over the past few weeks.
On one of the trips, I was by myself for three days of daytime driving (18 hours total.) This was something I have never experienced before, and I really enjoyed the Journey. It was an extended meditation: I listened to music, I looked at the scenery, I thought about things, and I drove. One of the things I thought was interesting, was how the scenery changed about every 30 miles or so. And I realized, that is about the extent of the bioregion.
When you have the opportunity to take a long car trip by yourself, try it.
When you have the opportunity to look at the scenery on a long car trip, notice how it changes. Notice where the Big Hills turn to the smaller hills. Notice the different trees and where they stand with different types of water. Consider the names of the small towns you pass along the way. See if you can identify where the boundaries of the bioregions are, along this route.
