I've been to Colorado dozens of times but always to the Rockies. A distant relative (a cousin of my grandmother, I think) decided it was time for a family reunion and hosted the event on his farm in Hugo.
My residence in Kansas City, MO leaves me within sneezing distance of the great plains, a region I refer to as "Desolation." We, my girlfriend and I, began driving around 8:00am and, due to lack of visual stimulation, she was sound asleep by 8:02.
It wasn't until sunset, as we, and nearly 100 strangers who shared some bit of common ancestry, stood around a homemade cannon that shot bowling balls out over the winter wheat, that I realized what, exactly, it was that attracted people to life on the prairie.
I'm a firm believer that there is no green so pure as that of the jungle. Similarly, I now know that the rich colors of Eastern Colorado sunsets thrive because they have so much space to play.
