Walk MS

I'm planning to do the Walk MS this year.  It will be the first time I have participated and my son said "Mommy I will walk with you".  So, I may get him, my father and possibly my other son to walk too.  Only my immediate family in my household and my parents and brother know about my DX.  I'm thinking about sharing with a couple of friends.  I just don't want the information to get out at this point.  There is a lot of things going on at my job with reorganizations and job cuts.  I know I shouldn't have to worry about any possible impacts because it is not legal to discriminate but people are people.  Anyway, I need to decide if I am going to join an old coworker my my teenage years' team or create my own.  We normally do the March for Babies ever year which is a big event.  The Walk MS will be a couple of miles from my house so it should be fun.  Anyone else doing the Walk or have participated in the events in the past?  Just curious.
