There are only about 800,000 people in SD. Quite a few of us are working more than full time, even at advanced ages for some of us!
My guess is that our taxes are spent far more frugally than most, given a relatively high degree of local control, low amount of governance on the county level (west of the River, anyway), and with the Gov we have now, frugality and quality spending for good results has been his history in rescuing at least one fine charity, and in his personal and business life before politics.
Just a somewhat educated guess, but believe that float is a package deal, which the Tourism Board, or possibly the Tourism business assoc. was involved in choosing, and may or may not be a txpayer deal.
