                   variables = "B19013_001",
                   geometry = TRUE)

## get state fips as its own variable
us.data$state <- substr(us.data$GEOID, 1, 2)

## filter by state (get two states)

## create a histogram of each with ggplot2

## create a density plot of both on the same grid, then modify colors,
