I just have to say, thank goodness we have side yards. I lived in a townhome community before and we had to keep our trash cans inside the garage. Believe me, there were hundreds of "trash can anarchists" in my neighbourhood every summer because no one wants to smell a trash can that's been baking in the garage all day in 120 degree heat!
On another note.. I saw H&N cleaning up some of empty house's yard yesterday. They did a good job. It definately makes the 'hood look nicer.
