What is this?
And what does it have to do with what I was doing on Saturday?
Clue #1. Posted 1:22pm Sunday. I did something yesterday that I had only done once before in my life. And the thing in the picture is related to that activity.
Clue #2. Posted 5:24pm Sunday. It's clear that many people are having difficulty working out the scale of this object. Guesses have ranged from a very fine file to a roll of carpet. Redstar's guess of a golf club grip is the nearest to imagining the correct size. It is cylindrical, about 4 inches long, and just under 2 inches diameter. It fits comfortably in my hand. Both ends of the cylinder are connected to other things.
Clue #3. Posted 6:04pm Sunday. What I was doing was done outdoors.
Clue #4 Posted 7:33pm Sunday. I wasn't actually holding this thing while I was participating in the activity. But the object is what makes what I did so unusual for me.
Clue #5 Posted 11:05pm Sunday. 5000.
Clue #6 Posted 7:08am Monday. I brought this object home with me.
