Taking the 69.61.40.33/28 subnet a bit further, .36 drops at 68.86.84.70
but .37 - .39 make it.  .40 drops at 68.86.84.70, but .41 makes it.

You're not the only one who noticed this.

"Thousands of tired, nerve-shaken, over-civilized people are beginning to
find out that going to the mountains is going home; that wilderness is a
necessity; and that mountain parks and reservations are useful not only as
fountains of timber and irrigating rivers, but as fountains of life."
