I've never been to Chicago and may be dooming myself in my response.But,the 21 miles home-I'm going with the urban setting-is not "as the crow flies" and therefore my journey with probably be no more than 10+ miles.If I know the area(I would hope to)I would already know of any police stations,Wal-mart type stores,Pharmacies,Friends and family members homes that are between my work and home if I would be travelling in a relatively straight line.Given the urban setting the tall buildings should give some protection,depending upon wind direction,in between any stops that can be made.I would try for a place where I could ride out the storm and get a ride later but if snow removal is a problem I would be stuck either outside anyway(when the store does close) or left at a friends/family member home until road/bus traffic was an option.If I was able to obtain or already wearing good protective clothing I would most likely continue until I made my way home.Again,never being in Chicago I may be a popcicle by days end. <img src="/images/graemlins/blush.gif" alt="" />
