Foster to adopt teen girls??

Good afternoon! DH and I are coming to a close with our classes. YEA! We have been speaking alot lately about teen girls. From what we are told there is a great need for this area. Our classes have had a goood bit of discussion with "protecting" ourselves from any false acusations. Are there any foster parents on here that have had experience with teen girls that can share with us? Like whether it has been favorable or would they never do it again........ Thank you in advance Fran
