Another suggestion. If you intend to drive the Going to the Sun Road, drive it from west to east. Its a two lane road carved out of the mountain and you want to be up against the mountain, not the edge. Its a long way down. Google "Going to the Sun Road" and look at the pictures.
Actually you are on the drop off edge side of the road going west to east (from McDonald lake to St. Mary Lake). Unless you also plan to drive all the way around the bottom of Glacier on route 2 to get back to the other side, you are going to drive the Going to the Sun road in both directions anyway.
Just in case you don't already know, large vehicles like RVs aren't allowed on the Going to the Sun road. When you drive it, you will understand why.
