That's a good idea.

TIP : Along with your Quick Fix 4.0 stash you might want to invest in some ThermaCare heat wraps ( PLUG ). Not only are they cheap but they heat up fast and they look innocent. Unwrap one of those babies ( air activated so will only heat upon opening ) and strap the sample to your body. Then just tell them you can't go RIGHT then and wait for it to warm. VOILA! Hot, clean sample! Good luck, d00ry!
