Composting in the city

Composting in the city

Howdy -- I'm sad that my first ever post to this lovely community concerns the yucky topic of rats, but here goes. I would REALLY like to compost in my backyard. I have a pretty good sized garden in one of the more suburban parts of Baltimore, but I do think we have completely escaped rodents. I know that there are supposedly special composters you can buy on the market, but I'm skeptical about how well they work. I'd also prefer to have a more homemade system if possible. Have folks created any cool systems in the city that work well? I have so many big trees with leaves that should be fed back into the earth, and of course all the food leftovers and other yard scraps. I shouldn't have to buy compost! Thanks in advance for both sage advice and commiseration. I promise to post pretty flower pictures at a later time :-)
