I finally had to stop listening when he was doing the part-time thing from Manilla (or was he still doing some weekend shows after he came back, I forget the timeline).
When Art was just doing just a few weekend shows a month, he seemed to only be doing what must have been his favorite subjects - consciousness, after life, Hoagland, remote viewing, and so on, instead of a broad range of subjects one would need to do to fill 20 some shows a month.
Turns out the subjects he was most interested in were the ones I had usually skipped in the past. The last of those I listened to was some new age chick going by Starfire Tor. I finally had to turn it off and leave it off.
I think I listened to a few Dark Matter shows, and maybe one or two of the After Midnight shows.
After all the begging for him to come back, clearly he should have stayed retired. But at least we know, instead of wondering what a return would have been like.
