Help:
 
I am giving a talk in Dec. ESA in Dallas on using observation hives as a
teaching tool. I have a few slides and will take more this summer but I would
like to see if anyone of you out there have some good slides of using OH's in
classrooms or other illustrations.
 
If you do and want to share them, please contact me direct for arrangements.
 
Thanks in advance
