I wonder the same thing. I only know of (or seen) one ku dish in a backyard. I know where 6 Primestar dishes are (2 are oblong, 4 are oval), and wonder about them. They all appear to be pointing at high noon, I'm at 83.7w, so I'm sure they're still pointing at where Primestar was located. I believe Primestar was on K2 and it was around 83.0w (maybe 81.0w) at the time. On another note, there are C-band dishes everywhere. I can't help but wonder if they are still in use. Some are obviously not, being pointed in wrong directions, like North, or at the ground, or pieces missing and/or obvious damage. But, most appear to be in good shape, and kept pretty well. One has recently been painted.
