You are correct in that Horace Williams has been in trouble for years. I was based there with my Ercoupe from 2001-2003, and was actually officially kicked out at one point (still have the certified letter from the UNC general counsel, which we all essentially ignored while the battle played out), as UNC has had eyes on that land for some time for a research campus (I think "Carolina North" or something like that), as they own the land and the airport. On the other hand the North Carolina AHEC ran several (4 or 5) Barons and a King Air shuttling medical staff to outreach clinics around the state that was really popular with the general population, so that provided a stay of execution...
Anyway, KIGX is very convenient to Chapel Hill, being only about a mile or so north of campus. Not much in the way of services, except gas, but as close as you can get!
I have very fond memories of being there, and if it is ever shut down (a la Meigs) it will be to Chapel Hill's loss!
If Chapel Hill is your destination, you can't beat KIGX!
