I would love to go visit the Wolfskill experimental fruit orchards in Winters, CA, but I have two questions:
1) When would be a good time to visit?
2) How do you arrange a visit? I looked on the Wolfskill website and the only contact information I could find was for Katherine Pope. I emailed her, but received no response.

http://www.ars.usda.gov/pandp/people/people.htm?personid=44926 Is the fellow that is in charge of the USDA program at Davis.

Be advised that they often cannot accept visitation requests because is limited personnel, and may not respond for the same reason.

Message has been sent. Crossing my fingers and hoping that I get a reply.
