Yes, you said E-streets. But I'm looking for any differences and things to know before making selection. Again, not just for me but for any that may reference this thread in the search bar a year from now.... unfortunately it was pushed off the rails so I now doubt a person will sift through muddy waters looking for hidden coins... But thanks for sharing, the photos help! :)
