I was going to get back to you with some of the organizations available to "at risk" and "crisis" teens. Here are just a few:
Treehouse in New Hope, MN.
New Life Family Services, MN
Homeless Shelters, USA
Teen Challenge, MN
This is just the begining of a long list of resources to get teens on the right track. These are also great places to give both your time and money, if you don't already have an organization you are currently giving to.

Remember homelessness or crisis is not that far from each of our lives. It could be reality for any of us at any time.
