I have found a way to get a little shuteye while riding a bus by tying my hair in front of my eyes and making it into my makeshift eye mask.
A suggestion: you don't want to try getting any shut eye on the bus. Around here you're liable to get jummped/mugged/robbed/etc.
This is in New York.
I agree. Google "Sasha Fleischman", pictured above, to learn more.
