In the mountains or for one hell of a dirt bike ride. It depends on what needs to be thought out and how uptight and emotional/antsy I am from the issue.
If it is basic issues--mountains. If it is super heavy and serious, dirt bike -WFO on a level 2 trail.
There is no time for the B.S. that comes along with the heavier issues when you have that much at risk if you wreck. I am able to think out the bottom line and sort through the important parts on short breaks--then when it starts to get muddled with the emotion--grab a handful of throttle and away I go.
