Almost all the roads going west off of Rosa Road to the lake are closed with locked gates during all the hunting seasons. I was just in 2b in early November for the second time in the last several years helping a buddy who drew tags there. One thing I can't stress enough is to take all the supplies in with you that you'll need for your entire hunt along with some extra in case the weather keeps you in past your planned departure. Make sure and take plenty of extra gas, water, food, and chains for all four tires for your 4 wheel drive PU that will be needed to hunt the unit, especially that time of year because once you get into the unit you'll be hours away from any services. Cell service is spotty, but we did get up high and were able to get Verizon and AT&T service from some spots. Concentrate on area roads you can walk into off Rosa Road on to the west toward the lake as we saw a lot of deer there in the nw part off the end of the road where the gate was closed. The further you can get in towards the lake the better you'll find it. Be prepared for jillions of gas well pads, compressor stations, etc. as you are never out of sight of one! The animals don't seem to be deterred by them though, as we saw a lot of them out in those openings. Get high and glass, glass, glass, and glass some more.
