  21. "I have two boys in the Boy Scouts, and I am a scout leader for our troop and pack. As scouts we do a lot of activities in the forest and have many badges that include forestry (we also have forestry badges). To teach the boys about forestry I have used your tree ring photographs on many occasions. Your photo's make it easier to
    show the kids the basics of tree growth. They are so useful to show the effects of the environment on their growth. Your pictures of fire and flood damaged tree rings are invaluable. I could never find real examples on our camping trips.

    Once we do class room at our meetings I try to follow that up with some hands on activity on our next outing. Your stuff makes for great class room but there's nothing better than getting in the field and have the kids look and touch. That's where real impressions are made and maybe a few memories as well."
    - Stephen Sarutto, Troop/Pack 150, Staten Island, New York
     
  22. "I am really happy with the information which i m getting from this site. Whole dendroclimatic information is arranged in a suitable manner so that one can cover all information regarding this subject. I am really thankful to you."
