Nice and cool here last night, I will get her ground up later today. As a side note I also was using a new pair of Binoculars, Bushnell 8x32 perma-focus and I was happy with them. They stay focused at any distance.....kind of cheaply made but I liked them because of not having to focus when looking through them. I think if you are going to be doing a lot of glassing and an 8x will do its $40 well spent.
