Look for cars, colors, models and take a mental note. Turn and keep turning, do a stop at a grocery shop, go to a barber shop, do your everyday errands, this way you can sure that nobody is following you.If they know what they are doing they might be following you like two or three cars behind you.Alternative to N4, much simpler and neat:Use a mule, give him an aluminum lined priority envelope (or box), and whenever he receives your package, instruct him to repack it in the specially prepared faraday caged envelope as soon as he picks it up, and redeposit it in a mailbox for the re-delivery to your real drop site.You can have prepared a bunch of dummy envelopes with similar weight and shape delivered to bogus but existing addresses. Put all these dummy envelopes and yours in several mailing boxes: and you just to made the LEO's day a nightmare: they will not be able to get a warrant, and if they planted a tracking device, it will be absolutely useless.Btw, always use gloves when doing this, from start to end.Interesting post, a few observations/critique:Building a booster bag is a non-trivial assignment. I know I advocate Faraday Cage devices from before on pickup assignments and it sounds stupidly simple, but as any ORC team will tell you there's two practical problems that catch you out.1. You need complete enclosure or it doesn't work.2. If you're serious about blocking the signal, you require >30 layers. You need to block from single digit hz to Ghz!To do it properly you need to alternate layers of plastic/alum in those layers. The best way to achieve this is to obtain plastic wrap, this is the kind kids use for covering their school books or copy books. i.e. big sticky roll of thick plastic wrap. Obtain the longest rolls in width/height you can possibly get. Now, obtain an alum foil roll, the kind used in industrial kitchens. It is thick and long, so it should fit the plastic roll. Finally, use a rolling pin to attach the foil to the plastic. Make up an entire roll of this. It's very fast considering how long it would take if you didn't do this.Now you have more than enough raw material to build a seriously good booster bag.The other problem is enclosure. It would be a pity to throw away the magnificent bag you have created so use some leftover 'booster roll' to make a top flap and then use a tape, thermal tape I think it's called, to seal the flap in place. Recycle! You could try Velcro too I suppose. Always test with mobile phones and other communication equipment to make sure you did it right.--An alternative to the alternative is to arrange a swop. Since you're meeting this mule anyway, why don't you obtain an identical outfit (and similar looking fellow), bag, the works, I would recommend wearing a cap/sunglasses. Then you meet up in some public toilet e.g. at a bar/restaurant/shop and arrange a swop. He dresses up as yourself, grabs a very similar appearing bag and wanders out, goes home and watches bugs bunny. You bide your time and change your clothes to something different. Pop the booster bag into another shopping bag and make your escape 15 or 20 minutes later. This way you don't have to deal with the paranoia of "is somebody following me" and your pal gets paid to watch bugs bunny at home while LE looks on somewhat mystified at this amazingly relaxed 'drug dealer'. The best thing would be to call a taxi to the front of the shop and walk out using passers-by as cover when you duck into the cab. This decreases the odds of a street interception team finding your destination to near zero as far as I'm concerned.Benefits:- no concerns about fingerprints.- don't need to trust mule with product or 'lost in translation' occurrences.- no postal costs- you are not posting a booster bag through the postal system.
