Yes, I did post out of 35. I'm finally going with a 5 X 7 (5 Across, 7 down). Only 2 or 3 GAL issued squares left. Why 2 or 3? I'm still debating on the dragon square.
Square #28 takes me back to me teenage years. I was first introduced to Douglas Adams in the early 80s, when a local radio station broadcast the BBC Radio show "Hitchhiker's Guild to the Galaxy", which included an edited version of the first three books of the Trilogy. Since, I have read and listen to all 5 books, plus a sixth book released by Eoin Colfer, which makes 6 books in the Trilogy. If you are familiar with the series, this isn't as confusing as it sounds.
If your trying to figure this one out, that is a thumb and fingers over a planet with a ring.
Now, do you know where your towel is?
