Well, I'm finally back after a long and thoroughly enjoyable vacation. I was down in Puerto Rico for some sight-seeing and hang-gliding. The most exciting event of the trip for me was my first mountain solo.

And the mountain solo was a beautiful, peaceful eight minute glide, totally unlike the Cannonball Competition whose solution is up after a bit of a delay.

Expect a new puzzle and the solution to the current puzzle in the coming days.
