G,
My girl and I, along with out two sons will be in the 13th. My son turns 19 on the 13th. He has never done a night dive and is a rookie w/only 6 dives under his belt (although he is very good in the water, life guard certified etc..), My girl has one night dive, but 40 some dives under her belt. Her son is sixteen and has about 30 dives and three night dives under his bed. I have only about 60 dives with two night dives under my belt. I just asked the B-day boy if he would be interested and he said he would. Our only concern is if you wanted to hook up w/a bunch of rookies like us to do the dives! We are only open water certified, but it sounds good to us, unless you wanted to do something advanced with advanced divers.
