Oh wow. I've been out of touch with Bob for decades. For a little while there we were both active in the Loglan community (this was before Lojban). I remember once riding my bike from Belmont, MA to meet Bob at some little airfield, where we tossed the bike in the back of his two-seater Cessna and took off for a Loglan meeting somewhere north of there (New Hampshire?).

RIP, Bob.
