Rod, the night dive originally scheduled for Devil’s Den may now be changing to Blue Grotto. One of the owners, Kurt, offered my group a "one time only" special rate which would require only 6 of us (myself included) to dive there on Wed. Aug. 6th, for $15. + tax, each, rather then the 10 needed for DD. Typically night dives at the Blue Grotto cost the same as the day rate, which is $40.
Being that you’re only the 3rd confirmation thus far, with 10 pending, we may have to dive BG anyway, as it doesn’t look like we’d have 10 for DD anyway.
