Have you noticed a few of the recent changes to sectional and TAC charts? Here's one that I was happy to see.
Item B shows RP 36 for French Valley airport, indicating a right pattern for Runway 36 when it's in use.
Since left patterns are standard, all runways not referenced have left traffic.
Neat eh?
