You don't get many days like that, glad you had a good one. Funny how the memorable flights generally aren't ones where you did this and that for the first time.
I remember taking an aerotow to 6,000 one summer evening about 9 pm. No lift around at that time except for the heat coming off woods and forests which gave some zero sink. The air was as smooth as silk and the glider felt like it was on rails. I just let it fall slowly out of the sky at min sink in virtual silence. It took about an hour to get down as all the lights were being switched on below. The clouds were catching the sunset and I felt as close to nature/the divine call it what you will as I've ever felt. Absolute magic and unforgetable. Makes all the flogging around circuits etc worth it.
You can't share these moments with anyone who hasn't done it really.
