Went diving in Maui & Hawaii in July - lots & lots of sea turtles - they're really cool - also there's a black sand beach on the southern tip of Hawaii we saw a lot of them where they come on the beach to rest. I'll see if I can post some pics on this thread when/if I get them off my dead laptop's hard drive.
One really shouldn't handle the turtles IMO, dolphins either. I know in FL it's illegal to handle or even feed wild dolphins. We tend to leave the wildlife alone when diving, just observe (esp. the sharks!)
For anybody into diving I highly recommend the Manta Ray night dive in Hawaii. Incredible!
Funny thing about Hawaii though - diving costs approx twice what it does in Key Largo. Can't figure it out. Fuel costs about the same, high real estate, high food prices in both places.
Interestingly I didn't find food & lodging costs to be that bad in HI, but it seems it cost about $100 per person to do pretty much "any" activity in Hawaii. One reason I won't be back soon.
