Housing is considered "affordable" if a family pays no more than 30% of its monthly income for total housing costs. Nearly one-third of Centre County residents pay more than that--sometimes much more. On this edition of Take Note, we talk about the need for affordable housing. Also we learn about the Allegheny Chronicles, a brand-new, online archive at the Warren Library with hundreds of rare images that document the Allegheny River. Guests: Linda Marshall & Penny Wolboldt
