What am I overlooking? There has to be a better way to manage my autumn migration. If I moved 50 miles south of here I would probably escape the smoke, according to airnow.gov. But I resist going into Nevada. Besides, where will the smoke-blob be tomorrow? The westerly direction of the wind on most days is all that we can rely on.
I am probably not the only seasonal migrationalist who resists retreating back north for short periods. It is like a military general refusing to retreat!
In practical terms, retreats do increase your transportation costs. But perhaps this can be overestimated.
Instead of my usual pattern of pushing relentlessly southward -- despite local eccentricities in altitude, smoke, and latitude -- perhaps I should do tactical switchbacks to the east or west, while still maintaining a strategic southwardness?
