It doesn't matter what mood I'm in, but seeing an MS or MX with temp tags is an automatic pick-me-up. I saw three on my way to work this morning in northern VA and the feeling just kept getting better with each subsequent one I spotted. That's an anomaly for me which is why today stuck out in my mind. I was out of position for the thumbs-up gesture for each of them so I'm sure the cars around me were having thoughts about my driving. It's nice to see more people joining the family.
