Post up pics of old style pipes, bongs, chillums, etc. Here's a pic that's like a silver pipe I had in Morocco. I had to trash it before going back to Spain. But they never checked my luggage! Damn! I could've brought back kilos of great hash....
Near my house as a teenager was a bamboo Grove. We would cut one, section it like the one above, and drill an opening for a stem and bowel. Down at the beach on the rocks one could find barnacles galore. The shells have an opening in the middle... which proved perfect for use as a bowel. Once assembled it gave you a nice huge hit
Seashells make great ashtrays and for serving up ground buds. Back in my college daze, a roomate had one of these meerschaum pipes. We smoked many a bowl of great pot and hash in there.
