someone mentioned it earlier but it is the cameras for me... I try and keep my packages small enough to fit in a bubble envelope, apply stamps and drop in blue box...The receipt you are given at the post office for purchasing DCN has the date, time and register number... would be nothing for them to run the recording back and now they have your picture...Ultimately I would like to have a bogus credit card I could use to pay for postal services via the web... then I could apply DCN and such without worrying about my pic making the most wanted list.TJ
