A) Occupation - Programmer (mostly database and corporate projects)
B) Commuting Distance - 20 miles give ore take 2 depending on route. (Quick and dangerous vs. slower and safe)
C) When at work - I change clothesin in a Handicapped restroom that used to be a shower

D) Where bike is parked - At a bike rack they installed where I used to lock my bike up (glad they had the same opinion of good places to lockup a bike! Very high traffic area would be hard to pull something off unnoticed)
E) Number of years commuting - Off and on for the last 15 years for a total of probably 6 or 7 solid years including the last two.
F) Year-round/part time commuter - Year round. No reason not to in Arizona (at least if you are in the desert and not the snow country, although I commuted year round in the snow when I lived in Flagstaff).
