I sincerely doubt I'll get anywhere near 100 days for 2025, and if I do, I'll not count this day...but I'm recording it for a "pat on the back" and as evidence of having performed a mitzvah. I dove into my local estaurine environment, with the intention of fishing (no pier available unfortunately) but when I left the house I grabbed a big plastic bag. I've been bothered by all the plastic crap littering this section of Baltimore County and the fact that it feeds into an urban drinking-water reservoir.
After I got to my "spot" (where I see another human being maybe 1x out of a hundred), I put down the rod and looked around for some discarded litter. This spot is pockmarked with hundreds of old, disgusting single-use water bottles along with other trash. After a while, with the bag about half-full, I recognized this as being an Exercise in Futility and went back to fishing. But from now on, every time I go to this spot, I'll carry a big plastic bag and grunt it out. Not that it'll make much of a difference, but...
Ain't I a mensch.
