Old guy (68), retired, native of Louisiana, recently moved to Texas by way of Missouri and Wyoming. Will enter grad school at North Texas in 2020 and begin with a marine biology course.
PADI certification is permanent; however, I got my Advanced Open Water in 1999, and haven’t dived since.LOL, I wish I believed I could pass a refresher course! At least we are working on getting out boat back on the lake!
Not being a scuba diver (and not planning to), snorkeling is pretty great, provided you can find a good spot!I have taken a couple of quick in pool refreshers but, truthfully, I am no longer a strong enough swimmer to do much more than snorkel.
