+## Overview
+Connect with board over serial, send it your coordinates, go somewhere. If you move too fast, you'll be disqualified, if you go to slow, you won't get there in time.
+
+Format:
+    37.430000   24.980000
+    37.430000   24.980000
+
+Destination 1:
+    Delftechpark 49, 2628 XJ Delft, The Netherlands
+    51.9979258  4.3834606
+
+Binary search speed allowed:
+    1 degree lat too big
+    0.9 degrees lat is fine
+    0.8 degrees lat is fine
+    0.7 degrees lat is fine
+    0.4 degrees lat is fine
+    Looks like I'm allowed 100km/h
+
+Positions are sent in degrees, but:
+	* It sounds like every message is an "hour".
+	* A degree of latitude is about 111km.
+	* A degree of longitude is between 111, and 0, depending on latitude
+	* The math to determine longitude give latitude is annoying, but easy to find and transcribe...
+
+I got it. Given a mission to South China Sea. Time to go real
+Grep for:
+```
+Location: 30.83 122.81
+```
+Know that, can take flights from:
+    CDG, PVG, SFO
+
+CDG: 49.0096906 2.5457305
+SFO: 37.6213129,-122.3811494
+PVG: 31.1443439,121.806079
+
+So, need to:
+    - write a semi-interactive tool, takes a destination from me, and goes there
+    - relays output to me
+
+Rest of the work is done in ``race.rb``
+
