I am out-of-county now, so I have not tried the bins myself, but when I thought I was moving to Annapolis I got the info. You can pick up a composter at this address I think, but you may want to call first.
Let me know if you like the bin if you get a chance--I'd like to know whether or not it's worth recommending over chicken wire and posts
