We'll call it a draw

So my slide rules need some definite attention paid to them, and part of providing that attention is slathering on some white petroleum jelly. The only difficulty here is that I do not actually possess any Vaseline and therefore had to acquire some. Even after 30 minutes in Walmart today, I still could not tell you where Vaseline is stocked there. Fortunately the mouthwash aisle had some in the little travel-size containers, which is more than I need anyway (since it's not as though I have that many slide rules). I am looking forward to soon having the slickest-moving slide rules this side of my front door.
