I had originally planned to just go and see if the gate was open on Black Star Canyon RD; It's not. It turned into a 7 hour adventure because all the trail gates are locked up by the Forestry service. And there aint no legal way around the gates. (great civil engineering.) Skyline and Leonard rds are all closed on the north side of the main divide road. I went up maple springs rd out of Silverado canyon and had to back track up sky line and then all the way from Sierra Peak. Next week is Lake Elsinor to Irvine over the Main Divide RD.
My stock 2013 Sport JKU did great. It's an automatic with 3.21 gearing and stock tires. I never mod anything until it doesn't do what I want it to. Main Divide isn't difficult but it does have a few hairy spots every now and again.
