Road "Stress"

No, it wasn't road rage, but it truly stressed me out! I was driving on a stretch of road between two towns that is a bit curvy, following a CDOT truck. This road has a 65 mph speed limit. He was going 45.....the whole way! The only part of the road that had a passing zone was very brief, and of course, traffic was coming towards me, so I couldn't pass. I could see the guy in his mirror....talking away to his passenger. Surely he could see me and the 5 other cars piling up behind him while he merrily took his time.
On my way home, after my errands, I got behind a guy who was maybe constantly checking on a baby or child in the back seat of his car. I could see him turning around every few seconds. He was also driving under the speed limit (and it was 35 this time!) and he hit his brakes before entering the intersection, although the light was green. I finally turned a different direction, only to get behind a cargo truck carrying who knows what, but driving under the speed limit again. He went straight and I turned, hightailed it homes I hope all the slow drivers are off the road when I take teen #2 to her volleyball practice tonight!
Like I said, I didn't enter the road rage stage, but I was pretty darned stressed!
