Scuba certified here with various add-on classes. Considered doing more or becoming an instructor but figured I enjoy what I have now why ruin it... Couple family members got certified before one of our larger family vacations. My daughter and I along with my niece got certified together. It was fun. Now on those family trips we all get out and do a couple dives together and it works out great. My daughter really enjoys it and is a great dive partner.
What I find more ironic is that I was stationed in Okinawa for 3 1/2 years and while I snorkeled and did a lot of spear fishing I never considered, or was scared, or something, to take scuba classes. TDY to Guam, Philippians, Thailand, etc. All places I'd like to dive or are known for good dive sites. All within reach and nope. I wait until later in life and learned in the cold, very cold waters, off the Northern California coast :) To be honest I've had similar trips like those mentioned here and it is a lot like diving in the bath tub. Warmth of course.
Every time I come back to the cold waters of Monterey and say to myself this is still the best diving in the world. Yeah I don't get to see the corals and reef fish we keep in our tanks but it is a different kind of reef and visual experience. A must for any diver. We go at least once or twice a year and do mostly beach dives. Point Lobos is epic. Monastery Beach Carmel, appropriately named, is top 10 dive site in the world due to the sheer depth, visual experience with the kelp forest, but also only recommended to advanced divers. I dive traditional wet suit 7mm with 3mm chest heater, 5mm gloves and boots. Good for three dives. Boat dives have at least one deeper dive first one out and that makes me wish I used a dry suit but, well, not my cup of tea.
Anyway - love to dive. Enjoy the breaks to warmer waters when I travel or go on vacation. It is a different world than what I see here near me or in Lake Tahoe.
