Jennifer has run a few triathlons this summer and really enjoyed them.  I even did one myself and would like to spend more time training for them next summer.  We both lurk on the Seattle Triathlete mailing list.  This morning, Jenn forwarded me a great little post:

So, we were out driving, when my wife pointed out a
cyclist to our almost-three-old son, "Look, there's a
biker."
Jacob's response?  "He must be all done swimming."
