all I can remember is that before I could leave in the morning to take care of my Things for the day, I needed to visit, in sequence, all of the Denny's restaurants in the town I was in. I did not know in advance what the required sequence was, but as I went from restaurant to restaurant, the right order and location would become plain to me, just in the nick of time.
however I did have one clue, which I felt inspired to draw. I had a map. and the right Denny's to visit didn't have the regular kind of sign:

but instead the right hand part of the sign was all modern-like, and that shape would appear on the map when it was the right time to visit it.

even so, I was still running late, and wasn't sure I could pull it off.
