anyone ever use any of these bags? usually for storing hunting close in, i was thinking that i should buy one so i can use it to transport my fall harvest from the grow site back to home....i guess i thought it might be a great idea and thought i would put it out there...i know i dont like when my car smells like ive got 10 lbs of freshly cut buds in the trunk....thought maybe one of these carbon bags would hold the smell....maybe even trick a drug dog? anyone ever use these?
