The horizon in that one picture is simply distorted, whether the fault of the camera or a weird rescaling anomaly. The curvature of the earth is much more gradual (it would barely be noticeable, if at all, in that frame).

I did some calculating a 1 degree slice would be about 70 miles. I dont doubt that I can see 70 miles of horizon from that point, but that is more curvature than 1/360 of a degree. Perhaps there is a slight variation in the elevation.

You have to do something like 8-9 thousand feet elevation to see the curve. (From Colorado Springs/Manitou Springs to top of Pike's Peak is close to 8000 difference, there you can see the curve, 1 inch at arm's length is 38 miles of horizon, etc)

That is still IM-PRESS-IVE! (the number of kins...!)

Don't know about curves and all that but love the photos of the patch Tom. Makes me wish I lived in real farm country again, almost.
Enjoy your diary entries. Congrats on the new nephew.
Was wondering, you call that a genetics patch. Is that for strain selection for future super giant AGs. Or is that strictly a market crop? What is the market for those?
Reminds of way back in the first half of the past century when I helped my uncles in the watermelon patch. They got a penny a pound for their crop. Hope you are getting a little more than that!
