I opened my weekend mail this morning and found a total surprise that has really taken me back.
Some time ago I had asked on this forum for some help on cumulus clouds. I was given far more help than I had expected. Then I opened my mail and found a sample plate, an inked drawing and a lovely hand written letter from J.J. Roberts. Here he had taken the time to go way more than the extra mile to help some one whom he has never met.
Thank you J.J.
