Thank you Stephen. I will take your advice. That way I'll get to meet
each individual berry on a more personal level ( before I squash it ).
I did have a bumper crop this year and it would be a shame to kill rats
and other varmin by having to trash them. I suppose a mildly soapy water
and a 3 inch paint brush to scrub with just might be in order.
