a) abandoning the course and going back home in a huff
b) doing the course anyway.
I went for option b and it was surprisingly enjoyable. Of course my time was more rubbish than normal, but without the compass I found myself aiming off and pacing more, and using these brown swiggly lines that were on the map.

At the end of the course my son gave the compass a proper teenage shake, and now it is fine.

I've got two questions:
a) What's happened with my compass? Is it going to stick again?
b) What would people think about 'no compass' courses? Making courses technically harder. Do any clubs do this?
