It'll blow Sunday. You won't be able to see jack shit, but it'll blow.
BTW, I have always had "real" jobs (even several 9 to 5'ers), one just had a split schedule allowing riding from 2-5 every single day.
I have found if you really want to, you can ride 3 days a week (if wind) regardless of your job. It's your personal life that might get in the way or suffer.
