The trash can story just reminded me of one from a couple of weeks ago.
Two points of note: One, we travel, a lot. Hence, sometimes we'll let the trash sit in the big cans for a week, since no one's home to bring the can in. Two, DP has an ostomy, so there's, um, pounds of poo in little sealed bags (which themselves are black opaque heavy plastic) that ends up in our cans on a regular basis.
I threw two bags of trash into one of our (new, no holes for ventilation) black large trash cans on a Friday. We went out of town, I wasn't home again until the next Tuesday, and we missed Monday trash day. One of the bags was kitchen waste (including a couple quarts of strawberries that had ended up being overripe and awful) and the other bathroom stuff (including the aforementioned poo bags). They sat in the can until the next Sunday night, when I went to add another bag to them and drag them to the street. Opening a sealed trash can with poo and rotten strawberries in it, that's been sitting in the hot sun ripening for a week.... I should get hazard pay. I left the lids off them for the trash guys, hoping the smell would dissipate.
