Montana sound pretty similar, This is it for the roads up here. The secondary roads are mostly dirt tracks. It's not really a place to enjoy a drive for the driving experience. It's a scenery thing. If you want to drive somewhere in a hurry it's a 'point and shoot' thing. Most of the 'towns' marked on the map are 'blink and you miss it' places. Towns of note are The Alice, Tennant Creek, Katherine and Darwin. You really just want to set the cruise control, sit back for the ride and try not to fall asleep.
