Basically what StumpyFSR said. I’d add in Bentonville and/or the IMBA epics in Arkansas, North Carolina and the Kingdom Trails in VT. Florida if you need a winter getaway in addition to riding (Santos, Alafia & Balm you can do 20 miles at each without much repeating, much more at Santos and Balm). Also check out where the NUE series goes, they have some good random race routes (South Dakota, Wyoming, Ohio, etc.)
