Forget the chain giants, this is the real thing, better wood, experienced people for counseling and custom cutting for the do-it-yourself weekend fixer-upper to big contractors. It's huge, with multiple giant buildings, one just for doors, one just for custom cutting and so on. And there's a friendly guard cat people come to visit in the hardware store.
