2. Everything goes better with wine

Nothing compensates for a long day of getting lost on goat paths in the wrong set of mountains like a cold bottle of white wine. Or a lukewarm bottle of red. The local plonk is inevitably a disappointment when you bring it home, but it always tastes good where it’s made. Many wineries in Europe will even fill your screw-top water bottles from a tank that looks like an overgrown gas pump. And it’s usually about the same price as gasoline - under $2 per liter. Of course, you can also buy good wines (already bottled!) at higher prices, but they don’t take well to the jostling of constant travel. Drink ’em if you’ve got ’em.
