While I never worked Larry on the air, he did process my KC4AAA QSL card requests. RIP, it sounds like he lived quite a full life and did a lot of good for the hobby as well as the South Pole. My friend is down at the South Pole pretty much every year and has also assisted with fixing things with the radio station down there. Perhaps you ran into him as I know he also mentioned that 17m antenna. I know he helped get the amp going and has also done some antenna repairs. I'm sure he knew Larry.
