Relay swim across Lake Michigan

I'm not an open water swimmer, but know one of the people taking part in a relay across Lake Michigan. A search of the forum didn't turn up any obvious previous mention. Apologies for any duplication. www.facebook.com/.../624784574201843 evanston.patch.com/.../evanston-swimmers-cross-lake-michigan-for-cancer-research The group is doing this swim in affiliation (I think) with Swim Across America.
