Wow, bad news...
Hardhats...I saw some volunteers removing some trees around a shrine this week...mostly farmers, I could tell by their trucks..
One guy had a hardhat, the rest baseball caps. I pulled my bike up and watched for awhile, then when a few of them walked by, I said, "You know, you guys should be wearing hardhats". One guy nodded, the others looked at me like it was none of my business and who the hell am I. I'm a nobody for sure, and wasn't going to fight about it. I took off down the road.
