From back when I used to do bike-interesting stuff.
This was actually something I imposed upon The Eberlizer, the rework of a completed rack due to my OCD nature.
I have never felt good about this (particular imposed re-work). Admittedly, the rack building program I ran out of my garage the past coupla winters was far from perfect, from a personal interaction standpoint. It's a tough gig, the School Of Rackufacture, as I'm not the easiest personality to be cooped up with in a garage. A natural-born teacher I certainly am not. But in my defense, the goal was to get some racks built by/for friends and some racks were most certainly built. So bite me about my lack of loveliness and warmth.
To the Eberlizer's credit, he was an amazingly good sport, because he is the Eberlizer, and to my good fortune, his loins never began to ache, as this would have sent me sprinting towards the house. I hope the rack, in general, worked out for him, somehow. The initial dry run is here (pre-rework), one of my most epic and impactful works of video ever . .
. . . and the experience appeared to be supremely positive, so I remain hopeful. That laugh of bike joy is about as good as it gets.
