I guess I'll have to start doing some backpacking again.
Perhapse that was the response they were after? A gentle nudge out the door for you?
I got my answer, and that wasn't it. They had a bit of a misconception about the hiking and biking I've been doing (a few hours at most), and thought it would be useful. But also because I've been doing a bit of travelling in (a) 3rd world country, although there's bottled water everywhere you look. But they won't mind if it turns out to be the gentle nudge out the door.
