I’ve been doing that for years… and contacted a lot of them via email back in the day… all of them replied :) all were super nice :)

John Varley was first… he asked how many got into sci-fi to begin with, and I wrote to him about how my mom was a massive fan of his and raised my brother and I to be big sci-fi fans etc… he wrote back praising my mom .. she was SO happy when I told her :)

Spoke with several others like Greg Bear etc… all of them were amazing:)
