I don't know how high the stacks are in Newgulf. My intent was to look right into the top of one but I chickened out today. Thursday at home, I flew my Spark somewhere above 320feet and lost it in the sky. It became so tiny that after I looked away, I could not find it. I brought it down thinking I could spot it but never saw it. It landed in my field and I used GPS from an image to find it. No problem there.
With this success, I will try again. The camera took this beautiful picture.
