It is indeed some species of Black Locust and indeed native to North America. Up here it's called Acacia. The official name is Robinia Pseudoacacia. Tree service is coming to take a look on Saturday on how to dismantle it.
This is a split of another scrounge (remember the old lovely lady I spoke about). It's the same tree as the one stated in the entry post. Verstuurd vanaf mijn SM-J510FN met Tapatalk
