Hi Petra. I certainly read the notes from the field trips that you and Don take and enjoy every word and it sounds like you have a great time. Perhaps I should have posted something about it instead of simply reading and enjoying it. I do know that you have contributed alot to this board and hope that you will continue to do so. There are alot of others that learn from you whether they post or simply lurk. I sincerely hope that I continue to read posts from you in the future. Take Care, Kate
