We feel terrible for the Family,what a sad thing to happen on a Great ,Fun day with Family and Friends.I didn't use a vest on our last trip to Hol Chan but believe me ,I will on our next visit in May.I know I got exhausted the last time and had a panic attach but Lil Alphonso got me back to the boat..Scared the Hell out of me...So Please EVERYONE wear a vest,if not for yourself but for your Loved ones..
