I actually am originally from California. I was born in San Francisco and spent a few years there. I moved around a lot because of my father's job though. So I lived in several parts of the US as well as Singapore and Guam. I wish we'd been able to go to Italy. When I see it on TV the architecture is so beautiful.
I missed the question about median salary. I looked up the median household income. There are no figures for 2013 (those will be released in September), but in 2012 the median income was $51,371. I don't know if that is before or after taxes though. I'm assuming after taxes. Incomes tend to vary by location though. The cut of taxes can vary as well. In some states the taxes are very high, but other states have no income tax.
Louisiana sucks-- at least the area where I live. It was fun when I was a child and I could just play on the farm with the animals. But now the economy is much worse here. Many of the places shut down in the town near where I live (I live outside the town in a forest-- well, it was a forest until the timber company cut down most of the trees).
I think the median income in the state in 2012 was $42,944, but I'm sure my town is much lower than that (I looked it up and it was $25,777 in 2011).
Are the tubes for an in-floor heating system using hot water? It looks like a lot of work, but you put it down nicely. It looks good!
