unmarked graves and free food

I left home a bit early yesterday so that I could go by the old cemetery and take a photo of an (preferably) unmarked grave. 
I wanted a photo that I could put  with a post about an idea I had the day before. 
I was thinking about the signature and especially about the signature of an illiterate person - the cross. It occurred to me that what we sign, remains. It's not just a very physical remainder but also in some ways a work that we have made on earth. 
That got me thinking of gravestones. They are something that remains but that others write upon or sign. 
Anyway, I ended up not having time to go by the cemetery but found that I had parked in front of one of our town's newish community gardens ( www.justfreefood.blogspot.com. )

I sat in the car looking at it for awhile, thinking about wild graves and what kind of marks plants and cultivation make on the earth and what 'remains' might mean in that context. 

So here are some photos of our community garden, for me today some grave heaps and humps and unmarked stones.
