Lime and Violet Sock Marathon

Hmmm... squares...
cast on 50 sts,
k 50 sts,
k 48 sts,
k 48 sts,
k 46 sts,
k 46 sts,
...
k 2 sts,
k 2 sts,
k 1 sts.
Plus two 4 inch tails.

# stitches = 50 + 50 + 48 + 48 + 46 + 46 + ... + 2 + 2 + 1
= Sum(1,50) + 25 + 1 (alternately: Sum(1,25)*2*2 + 1)
= 1275 + 25 + 1
= 1301

1301 sts on US size 4 needles... which are 3.5 mm... circumference? Nope, diameter. c = 2πr = πd... so 1301 sts takes approximately 1301π3.5 mm = 14 305.2421 mm or around 563 inches. With tails, that's 571 inches, or around 47 feet. Imperial has icky units anyway, so I won't bother rounding it to a nicer number.

Now, since I imagine there's more folks like me in this knitting marathon who really haven't a clue what a mile looks like, here's two photos I took out the window on the flight back from Montreal:


(The second one is from a lower altitude.) Back when the prairies were being settled, the land was divided into "sections": 1 mile by 1 mile squares. (More info.) For scale, those brown patches? They contain trees. Miles are big. My goal? To knit enough yarn to wrap nearly the entire circumference of one of those big, horking squares.
