Wow I was just thinking about this on my ride today. It was kind of warm 39. I live where it gets into the single digits in late January and early Ferbruary. Anyway, I tend to use my cycling gloves or just plain winter gloves. If I don't have gloves or my coat sleeve in the winter, I suck it back through my nose and then spit. I have been known to let it drip until I get grossed out if I am alone, especially at night. I tried snot rockets once and wore it, better off spitting.
