Independent editorial assessment
This spot’s an old school dig—boxes everywhere, but worth the rummage if you’re into vintage or junk wax era. Plenty of raw singles to sift through, not much in the way of slabs or recent sealed. The owner’s a talker and knows his stuff; if you’re comping prices, he’ll keep you honest.
