That is inspiring. Just last week I've been trying to get rid of some
on freecycle for a neighbor, some has brick facing in it from an old
garage floor. No luck.

I could find a use for it on my terrace, but there isn't quite enough,
and it would be too much for me right now anyway. Some needs to be
broken down more.

Think I'll go out and take a photo of the pile and try something else.
Just met the young couple, and they are incredibly nice, offered to help
me with chores in my yard, but I don't like to take advantage of people,
certainly might call on them for an emergency.
