Find-a-Grave has been very helpful in my family research. This site has linked me up with relatives that I didn't even know existed. The family names I am tracking/researching are my virtual cemeteries.
I enjoy taking volunteer photos - the exercise I get, the challenge of finding the requested memorial, and giving back to this web site. My volunteer pictures have come from 171 different cemeteries over four states. It is like the new F-A-G mobile app was created to make it easier for me to take volunteer pictures. I like that it leaves a GPS of the stone when I take the picture using my phone on the app.
You have my permission to use the headstone pictures without giving me credit. The people that use this site make this a great web site.
