Spotting at CHS (Charleston, SC)?

This may be something of a long shot, but I'm heading down to Myrtle Beach, SC in about a week, and while the airport there doesn't look to have very much interesting, I'm thinking of making a trip down to Charleston, where there's pretty reliably an An-124 that comes in during the afternoon. The other airline traffic doesn't seem to interesting (lots of RJs) but the airport is also an AFB so there's probably some traffic there not listed on FlightAware.

Is there anywhere that's a decent spot for spotting at CHS, that I could sit at for a while without being bothered, or would the airport being an AFB make that a tall order?

Thanks.
