To close the loop on my post.....I have now signed up for a PADI open water class in September. The timing for the August class wasn't good with school starting back the same week as the class.My wife will be taking the class in October. The school we're using only has one class per month and it would be tough for us to take the class at the same time due to the number of hoursWe should be able to get in a few dives together in early November locally and then we go to Tobago for Thanksgiving week for a few days so we'll do some diving together there.I was worried about the water treading test, but I just so happened to learn to back float just two ago after trying to figure it out for a couple weeks. Something just clicked and I was to float. Someone did mention I could have done drown proofing, but the instructors I will have prefers that we have our face out of the water and he said most of his students just float on their back. My wife can already actually tread water for 10 mins.....she tried on this past weekend to see if she could make it.Thanks for all the great advice and it nice to hear about so many other couples diving together. I have not shared any of these with my wife as I didn't want to put any kind of pressure on her or try to "convince" her to do it. She eventually decided on her own that it be great to do scuba diving together.DerekSent from my iPad using Tapatalk
