I think we can all agree that a schedule of 22 races is plenty for a open wheel racing season. Obviously we can't lump all races from the ICS and CC together to have one huge mega schedule so unfortunately some venues are left out. My suggestion is this....why not establish a core event schedule of say 12-15 races and rotate another 5 or so in and out every other year so the tracks left out of the established combined schedule are not lost to the tumbleweeds. How about something like this (in no particular order)...
Core Events Every Year
Indianapolis 500
Long Beach
Milwaukee
Texas
Chicagoland
Michigan
Cleveland
Elkhart Lake
St. Pete
Nashville
Kentucky
Montreal
Homestead
Events on Rotation - Every Other Year
Edmonton
Tronnah/Mosport
Richmond
California
Mexico City
Monterey
Sonoma
Watkins Glen
Iowa
Phoenix
Las Vegas (oval)
Belle Isle
