What do you consider a head-shop? In Five Points there is Natural Vibrations. It's a groovy place that always reeks of the most wonderful smelling incense. They carry lots of cool hippie stuff downstairs. Upstairs they have a modest collection of spoons and some fine, fine bubblers. Just ask to go up and they'll check your ID (gotta be 18). Their prices are very kind, the staff is very nice, and they had a real nice collection last time I was there.

I have bought all my pieces there. My current favorite bubbler is this 6-inch blue painted mini-bong. The bowl lasts and lasts and lasts. Paid a modest sum.

That's about as good as it gets in Columbia. Worth a stop upstairs definitely.
