In NJ there are a lot of the open air markets for heroin but many have closed down, i remember about 3-4 years ago you couldnt drive down the block without people asking or flagging you down, i recall the dudes selling use to fight over who is gonna serve me, they basiclly jump all over the car when they saw you coming down the block to the spot. Now there are still spots on the street thant sell but there are much less than there was,also i relized now you have to let them know that your looking to score since much less of people are flagging and shouting nowadays,I guess cause the cops have been cracking down hard trying to clean up the areas, But once the summer and warm weather comes around alot of those open air markets will open up again. As with any open air market you got to watch all corners and locations for the boys in blue and be as safe as you caqn, its best to go there with exact money you want to spend make the hand off and get the product and quickly but casually drive or walk out of there,dont ever stop and use near or close to any open air markets that just asking for the popo to come lock you up and impound your car.
