It may be early enough to correct a glaring mistake in your post.

You have included an unneeded apostrophe in "furlong's." The plural of "furlong" is "furlongs," never "furlong's." The only reason I bring it up is because it's becoming increasingly common to see this error.

And yes, I know this makes me a nit-picking Grammar Nazi, but when the time comes just put my on trial next to Lynne Truss and I'll face the music.
