Places to write in RTP: Observation Park at RDU.
Observation Park at RDU Airport is a pretty nice place to write because:
- No WiFi (no distractions)
- Large steel birds which should be flightless nonetheless soar and land with grace
- Air Traffic Control Chatter on the speakers
- There's a bathroom
- There are details on small aircraft to read, like flight range, capacity, fuel consumption, etc.
