For me the season MUST have these:
Interlagos - (despite not liking the lay-out as it's a glorified kart track it produces good races)
Season doesn't need:
Monaco - (come race in my backyard, it'd be more spectacular)
Barcelona/Valencia - (find a Spanish circuit that produces a race)
Would like to see:
Singapore - as long as the race is made less processional.
Would rather not see:
Hungaroring - (last few years haven't been too bad though)
Would Kill to see:
de la Sarthe
Future races WILL be in India and Abu Dhabi whether I like it or not.
