I don't remember which year it was, but the Tornado warning sirens have gone off in Chicago while I was on my commute home. I tried to get home before the storm could reach me but I didn't make it. Suddenly I was blown off my bike and branches were crashing down next to me. Thankfully I was close to the public bathrooms at the Wolf Lake and I was able to hide inside until the storm was over.
Yeah, it was scary and my wife was pretty worried.
