I have done vermiculture in the past with students and at home. However, it's been awhile. I now know several people who are potentially interested in starting worm bins and would like to be able to demonstrate a system--and later share worms. I assume it is too cold at this time of year to order worms. Thus I'm wondering if anyone near Friendship Heights DC has a bin that has extra worms or knows somewhere local that I can buy them. Thanks for any help you may be able to give me. Ginny
