Good little airport surrounded by hills on three sides so watch out. Check some details on Flabob Pilot Briefing . The gates are closed at night so it might be a challenge to get out.
The airport is very close to Riverside Municipal (KRAL). If you want to go south or west, or approach from those directions, give the cheerful folks at Riverside Tower (121.0) a call. The Riverside ATIS (128.8) is a good source of weather
The airport cafe is good but can be busy with locals on the weekend.
