Older single parent foster/adopt, DCFS

Any older single parent foster/adopt (DCFS), relative or nonrelative folk out there? I've seen a flyer in nearby small town library for a regional AARP (55 and older) grandparent group, but that seems only relative foster/adopt. Is there anything else? In my part of the state (NV), most or all of the foster/adopt groups and meetings are in the big city, c. 65 miles away. Any other rural/semi-rural folk out there? Are these conditions similar in other states?
