A Minnesotan will never tell you their opinion in a straight manner. If you're looking for advice you'd do better to ask someone from out-of-state than a Minnesotan unless you have a firm grip on the standard phrases.
If you were to say to a Minnesotan, "I'm thinking of taking a job in California that will earn me a six-figure income and a housing allowance on top of that. What do you think?" and he replies, "A guy could get used to that" then you know he's saying, "Go for it - live the dream!" If, however, his reply is along the lines of, "A lotta guys might ought not want to forget where he came from" then he's telling you you're being a fool.
"Guys" is another one of those funny words for Minnesotans. As long as someone is referring to mixed company, men and women alike are "guys". If, however, it's a group of only women they're "gals". Even teenagers use the word "gals" up here.
This is but a basic primer for understanding Minnesotan. Despite their stoic appearance, a Minnesotan is a complex creature and you can spend years observing their ways and still not have a full handle on the language.
