It's not just USAC MSCS,WoO and others change out on tracks too scheduling races are not that easy year to year each track has their own priorities on what dates are open week to week the same with Sanction bodies they can't please everyone, heck Putnamville didn't have USAC at all for about 5 years especially during Indiana Sprint Week they have their reasons of why and many of us know the reason and some don't it's just part of it and we all have to live with it.
