I explore the local areas a lot (hiking, biking) and try to meet new people. WWOOFing time tends to be bunched in to a few months, for example I'm on this farm in Norway for 2 months, so you start to settle in a bit which is nice when you want to focus on code.
But doesn't it completely alienate you from your surroundings? It sounds like you are changing places a lot. And I don't know about you, but my friends are the one constant in my life I'm really relying on.
