Rusty fences might warrant one.
Yes, within the last year. I thought it might be more of a cut, but when I finally pulled the sock off it was just a small scrape.
Apparently it's not so much rusty fences themselves as what microbes might be attached to them; at least that's what I was told when I fell on pumice rocks with my knee mid-2021. They're more worried about what might be attached to whatever you fall on/into when it makes a deep enough wound.
Right. I think I got my tetanus booster in April, so good for at least a few more rusty fences and whatever is living on them.
