Thank you again for the great tips, bambi47. Do you by any chance know the policy on actually being close to your belongings? I was quite a distance from my belongings..wallet, passport, etc...and could not see any of the testing. When I asked about collecting my wallet I was told not to worry. I could care less id they tested for whatever, however, I was more concerned with the cash inside. Everything was returned fine but you never know. Thanx again for enlightening me on this subject I have little knowledge about.
