Follow-up for posterity/ reference next year:
USCG Tac Com on Marine 83A (157.175), coordinating the exclusion zone. Also a bit of related official activity on 16 (156.800) and 23A (157.150), plus the usual recreational "boaters" (to put it undeservingly nicely, in some cases) on various other marine channels.
Air Boss 135.650 (David Schultz Airshows)
Show Discrete 123.150 (used by Kyle Fowler, Patrick McAlee, & Scott Francis)
Golden Knights 123.475 air-to-ground
USCG 345.000 MH-65 demo air-to-air
Horsemen 136.575 (2-ship P-51 demo including Jim Beasley)
Thunderbirds 235.250 formation, 149.650 solos. Alas their show started about 2 hours late and was abbreviated due to weather.
NJANG 177th (F-16s) & 108th (KC-135) -- I never found the channel they used among the F-16s or to the KC-135 for that formation. I got hits on 138.200, 255.000, & 261.000 but it seemed to be after their fly-bys so it may have just been them heading back to base.
I didn't catch 242.400 today. I got something on 40.100 (saved as NJArNG UH-60s) but their SPIES/FRIES demo didn't end up as a part of the show, there wasn't any military rotorcraft other than the USCG MH-65s.
