Winston-Salem/Forsyth Co TRS unknowns

[NCFireman11]

I'm hoping someone can help me out. I've been working on a list of unknown Talkgroups on the Winston-Salem/Forsyth County TRS for about a year now. I've been unsuccessful in identifying the ones listed so by all means jump in or PM me if you are familiar with the usage/TG name. All TGs were digital except one. Thanks!

334-Interagency communications (analog)
33488-Events parking or Winston-Salem DOT
34448-possibly security for one of the buildings downtown?
34608-building maintenance??
35568-"front gate to gift shop". Tanglewood Park ops?
36528-???
36640-???
38832-"232 to 234"
38992-WS vegetation management?
39056-???
39088-Winston-Salem brush/storm cleanup?
39344-WS yard waste cart pickup?

Here are more unknowns on the WS/FC system:


34344-FCSO Narcotics 2?
42736-Fairgrounds operations?
42832-Fairgrounds Annex maintenance (maybe?)
42928-Fairgrounds maintenance
43120-WS/FC Schools Ops 1?
43696-?

Lots of unknowns and the traffic on these TGs is very sporadic at best. After hours of listening I can't make heads or tails about what the official TG name is.
