Searching a foundation

[1960vw- Manuel]

I need a little help from the pros! I found a vacant lot with a cement slab on it that once supported a house. That's my guess. It's overgrown on the outer edges but I can see what looks like a cement walkway that goes along one side of the slab. A few feet in front of the slab is a semi-circle out of gravel that I guess was some type of driveway since both ends face the main road. Also, two big trees , one on side, other in back. I don't know what type of building was there and I've lived here in Sac a long time! It's on the outskirts of town so I'm guessing it's old! Anyway, sorry this is long, but what pattern do I use? Do I start in front or back?

Hey VW I would start in the front and work my way to the back.Make sure you hunt around the tree's real good and close to the walk way's.HH,Tom

Do you see any place where they might have put up a
clothesline? Maybe between the two trees or the one in
the back yard and maybe a post somewhere? That's
always a good place to hunt.
