One of my parents work in a classified high security area where dogs sometimes smell cars 3-4 times a day. People there are not protected by law just like in "civil areas". If a dog gives a sign that it smells dugs - you'r going to jail and you are losing your job EVEN IF no drugs are found (possession is not required). I did not know this until last night and I had some quarters in that car! They are no longer there, but I am afraid the dogs will smell some remainder (dust)! I cleaned up the place with alcohol napkins, but I am still scared the dogs will smell it. Should this car pretty much be never taken to that zone again?
