I was driving to Boise from Caldwell and noticed one bright white blue sphere and 8+ red green and blue smaller spheres to the right of the first sphere. In the north east sky's over Ada county.

The single large white blue sphere slowly turned to 2 spheres then back to one and repeated this for multiple minutes.  While this was happening the 8 + colored spheres where slowly moving in random spots of the sky but maintained a very close proximity to each other.  
The drive takes 40 minutes from Caldwell to Boise and I watched them for that long.
As I got closer to Boise the larger blue white sphere turned to 3 and spread out horizontally but not I'm a perfect line.  The 8+ colored spheres desolved to a group of 3 to 4.  
Originally the spheres were over the northeast area of Ada county in what we call the north end.  They seemed higher than the hilltops of table rock at first but as I got closer they moved further east and even higher above the mountain tops.  
Then I went inside and went to bed
