Thanks, Mikell for sharing...I will discuss it further with my husband. A funny thing I thought would be worth sharing...while on our honeymoon almost 17 years ago, I went out snorkeling for the first time. I wasn't too confident in my swimming capabilities and my new husband assurred me that I wouldn't need a vest...that the salt water would keep me bouyant. I insisted on the vest and for the entire week wore it. On our last day I wanted my husband to get a picture of me diving under the water. I removed the vest and for the life of me, despite numerous tries, I couldn't even dive far enough under the water for him to get a decent shot!!! eek This was in Jamaica and since then I've never worn a vest laugh
