I have been reading all of the responses to my question of a week ago.
Though I have not responded to any replies I would like all of you to
know that I will tabulate the responses and post it for your consideration.
This will probably not occur for another week or so as I am playing
"catch-up" after returning from Seattle.  I wanted to take the opportunity
to thank you for all of the information.  Please keep those "cards and
letters coming."  They are of great educational value to say the least.

Sincerely,

Steve Hoagland
