I didn't find the 2020 version of this freebie until April of this year. I think they had run out by then, so hopefully we're early enough for this free General Shale 2021 calendar.
It's weird. I barely leave the house anymore. All days are the same and yet somehow I need this freebie even more. Is today Sunday? No, wait, it's Thursday. Or is it… crap, I've already forgotten the other … four?
