I think they're dead, Jim.

One upside to all the crazy hot weather we've had is that the worms in the bags should be well and truly dead. So that's nice.

44.5*C = 112.1*F.
My old meat thermometer is stuck on C.

I've flipped and flopped the bags over enough to get a nice consistent roast. 

Part of this week's chores is to move the sacks for dead worm dirt down to the front yard (to fix ruts from the worm delivery,) and by the road to encourage grass to grow. Maybe if it's not 90* one of these days.
