Sharon and I are off to take a SCUBA refresher class this morning.  It&#39;s been 20 years since we were certified, and about 12 since our last dive (which was in the tank at Epcot  <img src="http://www.cruisecrazies.com/community/images/forum/tr-emoticons/laugh.gif" style="vertical-align:middle" emoid=":laugh:" border="0" alt="laugh.gif" /> ), so we&#39;re a little rusty on procedures and dive tables.  Hopefully we&#39;ll get back into diving on our next cruise.  We also plan to sign the boys up for lessons on board the ship, so they&#39;ll have something to do on sea days besides sleep late and hang out in the arcade.
