Kudos to viewmtn, who was first to report the correct answer (8:39 a.m.). We'll embargo the answer until tomorrow and let other readers figure it out.

Congrats to Richp39, who has just honored viewmtn's point. That's two so far. A slow day.

OK, seems like Thorpe's Log, but I'm a little late reading the site today.

I think you meant to say Tharp's Log, Rangertoo. In any event, you're on the wrong track.

... and RangerLady makes four. Looks like this one grades out a little tougher than average.
