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".
My biggest fear is when I die, my wife will sell all my guitars for what I told her I paid for them.
