He never drove (despite living in L.A.) so they didn't get together all that much, but lots of phone chat and letters.
I understand he never flew either - always took AmTrak when he was on a speaking tour. Ironic for a SciFi writer. Make that (for me) the BEST SciFi writer (my son would disagree although he is a HUGE Bradbury fan - I read him Bradbury’s short stories before bedtime).
An absolute treasure.
