615 E. William St., Ann Arbor; 734-665-9600; 42degreesglass.com
Why is this joint called 42 Degrees? Because Ann Arbor is 42 degrees north latitude to the equator, duh. This shop is an art gallery as much as it is a head shop, someplace artists can showcase their handmade glass work in a classy retail setting. Unlike other art galleries though, you can also score incense, bongos, beads, rolling papers, and blunts.
