Tractors.
We used to oo and ah over every tractor we saw. We would sometimes stop and watch them work. We would talk about the color and the big tires and the job it was made for.
My husband and son took a trip to Texas and decided to count the tractors on the way back. My son lost count after 200. He saw more than 200 tractors in one day!
Not such a novelty to see tractors in our way causing "traffic" anymore. We don't point them out to each other or stop to check them out.
I saw a big one a few days ago. As we passed, I realized that we don't much bother with them at all. They are part of the landscape now. Broke my heart a little to realize this, partly because my little guy isn't so little anymore and partly because it made me homesick.
