True but it is no more insecure to pickup from a GPS location than it is to pick up from a mail box. After all mail boxes are at GPS coordinates also . Some really big trafficking groups even use anonymously controlled mini UAVs + GPS systems for picking up and dropping off drugs. One technique I have heard of is dropping multi kilo orders from mini UAV onto the top of big buildings with people on the top ready to grab and vanish into the building. Shit can be well hidden before anyone gets to the top floors and it is a logistical nightmare to go through an entire building looking for a package of drugs, particularly if it is like a high rise apartment complex or something. This shit is all way above my level, but there are some smart mother fuckers out there smuggling bulk drugs.
