I've been sitting on this one a bit, but wanted to give a shout out to the 
folks at Schoolkids' Records in Ann Arbor. They're defunct now, at least as 
far as how they were in their glory days, but it was a very inspirational 
place to shop once upon a time. The various clerks were not only helpful, 
they were also very funny -- including the lovely Lori Bizer (a former Mrs. 
Paul Westerberg) and brothers, Will and Pickle. My musical tastes were 
warped in some respects, and cemented in others while digging through 
Schoolkids' stock.

You can't go wrong with Mike Felten and the crew at Record Emporium in 
Chicago, either:
