Natalie: As far as the EDL (enhanced driver's license) goes, you need to put pressure on your Senators and Congressmen/women to push for this type of license through for your state. I don't see why Idaho couldn't get a similar EDL since you also border Canada. Your state legislature would have to start the ball rolling.
As far as all that cold weather you are experiencing, which is crazy at this time of year, some of that weather is coming east. Beginning on Thursday thru Saturday here in VT, daytime temps will dip into the low 70's, but it's the nighttime temps that will bring the chill. Suppose to get down into the high 40's at night (48 degs). Time to get out the down comforter again.
