So, how do I occupy myself on my upcoming bus trip?

[Guitar Woman]

Why not read the books I am currently reading, and in doing so vicariously live as Guitar Woman for a day and a quarter!

For Whom the Bell Tolls by Ernest Hemingway
Lord of the Flies by William Golding
Fear and Loathing: Campaign Trail '72 By Hunter S. Thompson
Hell's Angels by Hunter S. Thompson
The Road by Cormac McCarthy

Failing that, you could always ingest copious amounts of psychoactive drugs to tide you over during your travels. Kratom is pretty awesome if you have a spare 30 dollars lying around. Buy it at your local herbarium!
