Funny thing about old time radio

I know in my head that those old time radio dramas were done by actors standing at a microphone and a sound effects guy shooting guns, making horse noises and all sort of things.  But I get lost in the story a lot more than I do with TV.  Radio drama somehow become real.  You see the action and the people in your mind.  That's why OTR is called "Theater of the mind."  There could be no better description.  How sad that radio no longer does that except for a few groups and individuals who  understand that great medium and devote themselves to promoting, sharing and producing radio drama.
