Hello, John.

It looks like you are getting lots of advice for your poison oak.

I was wondering if you are the person I think you are.  If you are not,
please forgive me.  I have miss placed my list of names and addresses from
last summer's Permaculture Design Course at Tunitas Creek.  Are you the John
Knapp of Dental,  Safety Group Six and Tunitas Hula fame?  If so, please
write back to me.  If you are not, again, please forgive me for such a
strange message.
