Since I didn't work in the summer as a teacher, and now I am back in school, I am usually home to see the "live" broadcast in the AM. That takes most of the morning... I don't watch it everyday, though. Some days we watch the "expanded" coverage on Versus in the evening, but there are days when I will watch it twice, in the AM, alone, and with DH at night. When it is on in the AM, I don't usually sit and stare at the TV the whole time; I go about my routine things, housework, yoga, studying, etc, with the TV on a little louder than usual. If I hear something exciting, I will go over and watch.
We do usually get together with cycling friends on the weekend to watch particular stages. This usually involves mojitos or beer.
I always get a little sad when it is over. This means summer is half over.
