Hard to believe a city of 150 thousand can't support or doesn't justify a mixed GA and CAT airport, I used to spent time up in rural Alaska in the 90's and was impressed how shyitey wee fishing towns used to have at least 1 scheduled service of a 737 several times a week, I doubt if they were subsidized.
Shame really.
Edit to add, just bought that john kilburn book of Amazon, looking forward to what looks likes like an interesting read.
