Hopefully optimistic.  Don't bum me out going into a weekend...  :-)

 From the looks of my ingress BOGON ACLs on my borders (yes, I'm using
ACLs and not null routes for a reason) I'd most people not reading NANOG
(and maybe even some of them!) are not doing any ingress filtering on
their customer source IPs.  Sad....
