The slightly shady looking convenience store/smoke shop I stopped at sold me a pack of 32 6" pipe cleaners for $2.
I figure I'll throw them away when they're saturated and icky.
The shop had something for everybody. Pipe smokers, roll-your-own cigaretters, cigars, weed smokers, hookah, e-cig, etc. I saw jesty little mini corncob pipes for $1, grabbed one. I figure it's lightweight, might be easy to clench and smoke while driving.
