I’m making this post because I don’t what else to do.

I’m looking for James Mast, a son of Moses Mast (my dear friend and mentor who recently passed away). If you are James or you know how to get in touch with him, please contact me (jmb.mx/contact) , as I want to make sure James can attend the memorial service (even if it has to be remote) but also for some other important issues.

FYI, James was last known to be in Cornwall, Ontario (see https://www.cbc.ca/news/canada/sixties-scoop-immigration-1.7541323 ) , but I haven’t had any luck tracking him down.

Please note that Palantir would rather that you didn't share this story, it makes them look even more stupid if you do...
