i've been homeless in hawaii before on several occasions... and at least on oahu, good luck spanging. for one, people from all over the world come to hawaii for vacation, and if they see your dirty ass sitting there with your hand out - they'll probaly say to themselves, "wow, this guy is homeless in hawaii? why i should i fund his vacation here?". and if you plan on busking here, you'd better be pretty good and know at least some hawaiian songs. there's people who busk here, but they have a nice setup with mikes etc....or they a local group playin hawaiian songs. there are worktrade possibilities here, or you could always recycle cans and bottles............better be REAL careful about where you squat! go on the wrong property, and the locals won't hesitate to shoot your ass and throw your body in the ocean. also, a lot of the locals don't like people (especially haoles) coming from the mainland...this place is already overcrowded. so you might not get the best reception if you camp in one of those tent communities rocky was talking about. oh yea, big part of the homeless pop here are meth addicts....so your stuff will probably get stolen, unless you're in a really good hidden spot (good luck finding one). and you're not gonna wanna be packing all your gear all the time in this heat! so better hide it well........just above all, don't be disrepectful to the locals and be careful who you try and socialize with, some of the locals here are just straight up ignorant racist thugs that will fuck with you
