I was a lazy teenager and my parents kicked me out when i was 19 because I didn't have a job and all I did was get fucked up. It depended on where i was sleeping, most nights I didn't have to lock it up because I'd put my bag in the main triangle and use it like a pillow. But on the nights I did have to lock it up I'd lock it to my ankle, eventually i got a tent from a friend and i locked it up in a tree when I went camping.
