The pic with the oval leaves looks like a Locust of some sort..
I forgot to mention that I too thought it was some kind of
locust. But the big question will be - which kind of
locust? Black or Honey or some other tree like that such
as a Carob tree. So I have to taste the seeds
and see if
they are toxic. If they are not, it might be a Honey locust, if so, it might be a Black Locust.
For the other tree, the leaves are too high - I need to get a ladder to get a nice pic or use zoom somehow.
