I've logged a bunch of aircraft heading that way.
Two Canadian First Air C-130s C-GHPW and C-GUSI (one was at KIAD last night picking up another tactical rescue team),
Lynden Air Cargo C-130s N404LC and N405LC
Tepper Aviation C-130 N2679C (departed KMRB)
3B7B86 F-ZBMC Dash8 of the French Securite Civile Fireguard
Canadian Air Force C-17s 177702 and 177703, C-130 130343
and of course a whole bunch of US military transports.
One of the major staging areas will be KMRB which isn't too far away from me.
Here's a good way to track commercial C-130 traffic. N2679C isn't trackable though.
