Thanks for all the comments.
I think presenting them with this reminder of their farm is something these people will really appreciate - they loved the farming life.
I also took some video and will burn them a CD with that and all the pcitures I took as there are a lot more than the 9 we are using for the framed collage. I also intend to do the same for all their children so they have a reminder of the farm where they grew up! It should be a nice surprise (I hope!).
And just to clarify, the car will not be part of the photos going to my aunt and uncle. LOL!
