As club secretary, I led a fuel cost analysis that resulted in a restructured tow rate schedule. Apparently I can't turn off the economist brain at altitude.
There's something clarifying about being 3,000 feet up with no engine. The decisions are yours, the consequences are immediate, and the air doesn't care about your priors. It's a good antidote to desk work.
The best thinking happens at altitude with a thermal to find and no engine to fall back on.
