In your pic the corn's up top. I've never tried it that way, and wouldn't "think" it would cook enough up top when in foil?
For what it's worth here's an update.
5:30pm, lid thermo still pushing 375 despite intake no more than half open. Gave the intake another small nudge towards closed. Plenty of coals left.
Blue smoke gone. Well, the "smoke" was an experiment anyway.
Removed the grill, added more smoke wood. This last amount is about half the initial total, so likely won't last another hour. Don't care. -- We'll be eating this dried-out pork in an hour. Some has pulled away from the bone. Of course this is because of the heat, not the cooking time. Bummer, but then again what did I expect, starting LATE and cooking HOT?
Pork is left sitting on the foil. No sense in actually overcooking it. When I'm reasonably sure it's done I may take them out and grill directly for a few minutes to sear/cook done ...
I put the 6 wrapped corn cobs downstairs near the coal holders. Probably rotate the ones farther away in about 15 mins. Seems we'll skip the asparagus on the grill and steam in microwave.
The best corn I've had was essentially roasted on the grill, no husk, no foil, and today's ... not that day. Oh well.
