I stumbled across this article from the Standard Examiner the other day. Mike Stephens for his 48th Birthday swam one way from the tip of Promontory Point to the north end of Fremont Island (2.7 miles). You can read his own account in the link provided above.
It's cool that another person swam to Fremont, but I'm disappointed that the swim went so bad for him. He said he would never do it again. "Never say Never".
Maybe it went so terribly because he was ill prepared. Over time, he'll ponder back on the swim, how difficult it was, the satisfaction he felt in accomplishing something that was tough, and I'm betting he's either right, He'll never do anything like that again, or he'll grow from it, and take it to the next level. Hopefully the latter.
