I'm in Omaha, and I don't do too much to winterize (thank God for FI!). I really just put Sea Foam in the gas & hook up the battery tender.
But then, I'm the type who will ride in pretty cold weather. As long as there's no snow or ice on the ground, I'll go in temps down to about 20 (not very long distances).
I consider putting the winshield & crash bar chaps on and bustin out the neoprene face thingie to be "winterizing".
I know my greatest deeds will go unnoticed
And our treasures were here all along
