Hi!
I was so surprise to find this subject in your posting! Diving and Biking consume my life! I've been a professional diver for years as an instructor, marine researcher and model/photographer/traveller. Looking over your comments, I too find it difficult in keeping up with both sports. I got burnt out on scuba diving from teaching too much and turned to biking lately and have been enjoying it for the past year. I was thinking the other day how it seems that biking has taken over scuba diving. But you're right, it's always going to be a love and a passion. I'm slowly turning into both a fairweather diver and biker and a balance is a good thing.
Nice pictures by the way. In response to some of your postings, a refresher course is always a good thing if you haven't been in the water for 12 months or more. They're normally very cheap and easy. Even if you do get in the water often, it's also good to do refreshers so that you can keep your safety skills up to date!
Also, I've had many students that have been scared of the water, etc. Some of them have even been poor swimmers that took scuba lessons just to get over their fears. I highly recommend it. Scuba classes help you ease into the sport and if you tell your instructor immediately, he/she can help you overcome your fears. I've found for both myself and my students that once you start diving underwater, your fears of the water disappear because you start to see what's underneath and how harmless it is.
Good luck and have fun to both bikers and scuba divers. If you have any questions about diving, I'm happy to answer any! As far as biking, thanks to this website for helping me with gear choices and training!
