On a background of a recreational vehicle and a prevalent moon. We know by now that most things in these kinds of tweets aren't done without packing as much meaning into it as possible (images, timestamps, etc).
Note: May 18th is a full moon (pic related) and I'll toss in something else I've been prompted to consider.
The HRC video that was part of the Q-drop with "EX-rvid5774"
What if instead of "raw video"…"rvid" actually stands for "RV identification"? Just a thought. For that matter, "vi" is 6 and 6th letter is 'f'…not hard to get "rfid" (as in chip) out of that (or vf=Vincent Fusca, for that matter)
