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

Supposedly you can go to any of the dumps and get free recycling and compost bins, when we went there we re big piles of recycling bins, but nobody seemed to know where the compost bins were. I think I had even called first, but it was a while ago, so I'm not sure. Everyone did definitely agree they should around somewhere though....
