If the author happens by to read this, I wanted to maybe offer a bit of help with some of the 'in the field' frustration noted: >This time of year is sea turtle season in the southeast and the threatened turtles that come up on the beach to lay their eggs (and any little ones that hatch) are highly sensitive to light and often get turned around and disoriented by lights on the beach. For that reason, South Carolina (and presumably other states in the area) has instituted a no lights on the beach policy. Luckily there’s enough light pollution that you can at least navigate without a problem, but not being able to use a flashlight to help with focusing, adjusting camera settings, etc., is a bit of an annoyance. When I was in Costa Rica seeing endangered sea turtles doing their thing, the local guides used red bulbs because they were not disorienting to the sea turtles. Noise from the tourist group was killing me I gotta say but hey I was along for the ride in this case. Can say I learned the red light thing. So I looked up real quick and found some info and links from a South Carolina conservation group. They state the ordinance reads that "disruptive lights" are forbidden. Then they had a link to a site of 'certified' bulbs for use around wildlife. Red is one of the main colors featured: http://myfwc.com/conservation/you-conserve/lighting/certified/bulbs/ http://myfwc.com/conservation/you-conserve/lighting/certifie... Thus, using a red light may be okay under the spirit and way the ordinance(s) are written, but calling ahead might be a good idea too.
