Actually she did not respond for the first few minutes. My proposal came in the form of a Geocache hunt. She had no idea what I was up to and walked the coordinates to "Marry Me" in 100 foot tall letters in a field. The GPS was tracking her movements and at then end she could read what it said. Instead of saying yes she was asking how I did it and how long it took.

I am going to get a UK to wear geocaching in the future.
