I meant to post this yesterday. Ryan took this video on his way home from work. For those who aren't in flood-prone areas, the manhole cover that's trying to pop up means that the drains are full and it's about to start flooding catastrophically. I learned that the hard way when I first moved here. The streets were flooding and all of the manhole covers had popped off. I ended up in 2 feet of water and Ryan had to tow me out... So, now I am more cautious. Once the drains fill up, I pull into a parking lot or someone's driveway--it doesn't matter.
