Disclaimer: I have not read this thread so I'm not sure why the topic is rock throwing, in a thread about 3 seasons nests.
But... I was hit, dead center, by a rock in September of 2017. This was the first of MANY rock throwing incidents and I have recordings of most.
This particular rock hit me where men don't ever want to be hit. Lucky for me it was about the size of a dime. Based on the trajectory of where we found it, it had to have come from about 30-40 yards away and this location at the time was near pitch dark. I was taking a drink from a water bottle when it hit. Had I not lifted the bottle to drink, it may have landed in my hand.
After this 1st incident, the rocks that were thrown started getting bigger. None ever hit us (until summer of last year) but many were bounced off the iron railing of the bridge we were on for some real startling effect.
All of the recorded incidents are in that thread I just linked. For every rock incident, we were in dark conditions. Last fall I was there during a very bright full moon and we had zero activity. I presume they only get close when it's really dark.
in 2018 we noticed that several of the rocks were very warm, indicating that they almost certainly had to have been holding them ahead of time.
I say "They" having never actually seen a sasquatch throwing the rocks. I can say that with the manner in which I had my recorders set up, that no human could have positioned themselves to hurl rocks at us and also avoid discovery. The hidden recorder would have revealed them coming or going from this particular spot, as it would record every minute for a full week. In 2018 we also had a plan to light up the area with high power flashlights, and we had night vision and thermal, to try to catch the culprits when the rocks came. We still never saw anything. I remain confident that it was not squirrels, deer, raccoon, owls, or beavers that were throwing rocks in the dark.
Last summer, when I was not there, one of my friends got hit in the shoulder with a rock. He had just been complaining that he didn't have his own rock, so they seemingly delivered. I don't have recordings of that incident.
In a sort of related incident in 2018, something set off a car alarm while we were there and we discovered that the car tire had been peed on.
I would contend that when throwing rocks, in our case, they always hit what they intended to hit, in the dark. If there were any mistakes, it was the one that hit my friend in the shoulder.
