Historically, the 100th meridian separates the east side of the country where no irrigation is needed from the west side where it is needed. I have seen irrigation before I cross the meridian though.
Cozad is a small town right on the meridian and I went thru it today. Is it a coincidence? I have to admit still that in the 10 or 20 miles that followed I noticed some changes in the scenery, with less corn fields and already some prairies and few hills in the distance.
No surprise then that I get to North Platte in the evening, the home town of Buffalo Bill. I gave a try to stay at the camping next to his ranch; yet no shower, no running water. I am not yet that of a cowboy!
