I've seen a lot of stupid, but this one really, REALLY takes the cake for me.
I concur with Laura. I guess that dad thought that all vomiting stops (just like bleeding, one way or the other)
Once we were running down from Mammoth Crest to Lake George because of lightning. A dad was carrying a baby on his back up to where we had fled. He ignored our pleas. People do the dumbest things.
