alot of las vegas is relatively safe, but i would NOT be walking about north las vegas after sundown, nor alot of areas directly off of the strip or bordering casinos.
unless your mission is to buy watered down crack or get robbed.
thats all imma say about that.
theres parts of vegas where personally, i wouldnt even stop at a light.
and im not the locked door/window up type either. ill throw the peace sign at crack sellers.
