i roll with my homeboy and thats enough protection right there. if worse comes to worst spray a nigga in the eye with your paint. i've never really been messed with yo, most niggaz doin dirt on the corner aren't concerned with your ass anyways.
in my hood a lot of us ride fixed gear bikes so seeing someone with a backpack is not an uncommon thing. so im guessing you live in a environment where seeing someone late at night with a backpack isn't that big of a deal. get a chrome bag and fuck it ride a bike from spot to spot. its dope i can get across town to other spots easily and bounce quick too.
