My wife and 2 teenaged daughters went on this trip.  We set out at 10 PM and got back at 2.  There were many, many stars.  Way more than we see in Atlanta.  Night on the water is a whole different world.

Gigging is hunting fish with a pronged spear.  It is a whole different thing than fishing with a rod - we watched the fish go by in the spotlight which you cannot do with regular fishing.  We saw lots of fish that were not the ones we were looking for.  Many stingrays and squids.
Everyone was into it.  The mate got us a couple of fish and I eventually got 2 - the ladies attacked with their gigs also but it is not easy to spear a fish!
Mr Stevenson was wide awake, attentive and enthusiastic.  We used up the battery with the fish lights but he had spare batteries and so that only slowed us down a minute.
  It was a great experience - surreal being out on the water in the dark with giant spears in our hands,  but reassuring to be there with 2 regular guys who knew what they were doing.
