Dave in a funny position

This is not a typical napping position for Dave. It is really unlike any other napping strategy he has used. But there is one thing this strategy has in common with Dave's normal strategies: it looks very comfortable. It looks like the kind of napping strategy that would be effective in the winter months, so perhaps Dave is simply trying to prepare strategies well in advance this year. After all, last winter was quite severe, and as good as his improvisational skills are, he likes to be as prepared as possible.
