He says that he learned the importance of affordable housing during (drumroll please) his travel adventures.

I grew up watching Rick Steves. I still love watching his shows on PBS. But you never really hear much about him outside of that...until now.

Instead of putting his retirement savings into a bank, he invested in a $24 million apartment complex that would house single moms who are struggling with addiction recovery.

And now, he's taken it a step further - he's given the complex to the YWCA. Amazing. Makes me want to watch his shows even more!
