jetfixer:My buddy volunteer dives at the Aquarium of the Pacific. He keeps a seperate log book for his own personal records. So I guess its an "unofficial" logbook of cool memories of his experiences and accounts with the different animals he feeds and cares for. Also, you may want to look into the criteria for volunteers. I know at AOP, they require Rescue Certification, min. 60 logged dives and you have to pass a test and demonstrate good buoyancy skills in a pool.
Good to know for future reference. I should have Rescue by the time they would need volunteers,
Trip back to the Keys (was just there at the end of May) in July. I will get 6 dives minimum... and hopefully a few AOW check-offs done as well.
