Munroe numbers are the Geohashing equivalent of Erdős numbers.

You are Randall Munroe? Your Munroe number is 0.
Your Munroe number is one more than the lowest Munroe number of anyone you've met at a geohash.
(If there is no path from you to Randall, your Munroe number is infinite.)

Use the meetup graph to calculate your own number!

Example

Randall Munroe's number is 0

Zigdon met Randall Munroe at 2008-05-17 37 -122
Ted met Zigdon at 2008-06-01 37 -121.
Anniepoo met Ted at 2013-05-26 37 -121.
Thomcat met Anniepoo at 2012-08-21 37 -122.
GeorgDerReisende met Thomcat at 2014-02-23 49 8.
Fippe and met GeorgDerReisende at 2015-02-20 51 9.

Thus Fippe's Munroe number is (at most) 6 (unless a better connection is made later)
