No really, tell us how you feel. Ah the flight fantasy, this time its Brazil! Speaking as someone who logged over 1500 miles on crappy Brazillian highways this december; I can honestly say, lots of Brazil has very poor weather. I am also quite certain that the locals in those beach towns you are talking about are quite incensed about all those stupid foreigners who keep coming in and buying up all the good ocean view property. Its a matter of your starting point.
The only argument that seem to hold up over time about why housing is expensive in SD have to do with the climate. If you think Florida has better weather, more power to ya, but I don’t think most people would agree. Florida has even less months of pleasant weather, its usually far to humid and hot. Again thats just an opinion.
