I agree, and in fact, ride all year, including throughout New Jersey winters (unless there is snow/ice on the roads).
Since I've been riding regularly, i.e. for the last 8 or 9 years, my resistance has actually become much stronger. SInce that time I've no longer come down with my once per winter, generally late winter, flu/severe cold and cough. Of course that's just anecdotal, but certainly fresh air does wonders.
Best regards
