Day 4: 4 items - 4 items = 0 items

But I also realized that while I may not want to put the paper plates, towel, and napkin from the past couple of days into my own composter, I CAN put them in the city's green compost bin. So out of the bag they go and into the bin. I still can't reduce the size of my bag because of that danged plastic cake bottom.
And yes, I have been carrying my bag with me, but it fits into my backpack so no one has to see it. Is that cheating?
