August 14, 2021 Update: Well, once again, I spent most of this week working on the root cellar.  The main structure is done and covered with dirt, but I still need to make a door for it, and before I can hang the door, I need to build some more retaining walls to prevent dirt from getting in the way of opening and closing the door, and then I'll have to do some finishing work on the inside.  I'm tempted to give the project a rest for a while, though, as it will be easier to build the retaining walls once the dirt has had a chance to settle a bit more.
I did get around to making one video this week, testing the effect of pistol braces (on AR-type pistols) on practical accuracy.  The bottom line from the test was: If you're trying to shoot one-handed, an arm brace helps a lot, but if you're able to use both hands, then the brace is actually counter-productive.
Anyway, this weekend I think I will upload the video I made about eating wild fireweed.
