Are you saying you don't know where this happened beyond what the ticket says? There is a "Bootleg Campground" off the 395 about 10 miles south of Walker, and the 395 is a two-lane highway for most of that area. However, if you believe that it was not a two-lane highway, you're free to challenge the ticket. However...
You were admittedly driving 22 mph over the posted speed limit. What do you think you might accomplish by fighting this?
I suggest you take care of this with traffic school if that is an option.
