You will be astounded by their work. Their generosity is legendary. Your nose will burn as you spray hot coffee through it from laughing at David! Mort and David are two of the nicest people you will ever meet, and are down-to-earth. You will enjoy them. 43 years in hybridizing! I HOPE I can have a few seedlings in the next 43 years that are remotely close to their early work! Of course, 43 years from now, I won't even be able to see them!
