If you were a bum, where would you live?

When I was a bum I slept in my old school.
Arsenic walls but working water and electricity

 

Not sure where I'd live, but I'd bring my guitar with me. Then I'd be able to busk during the day to make some money. I'm sure I could make enough money by busking to feed myself each day, probably with money left over. But I'd also need to find some sort of way to keep my guitar safe while I sleep.
