Here's the obvious for some. Never have like 10 guys standing in a circle singing kumbayah on 4-6" of ice. The new version of frozen kumbayah was not a hit. And don't go telling others the ice is safe in those conditions like I did last January. Some folk take you out of context and make you out to be a monster on other forums. That's when mob rule really comes into play. They're like sharks in blood stained water circling their victim eager to take a chunk out.
Never go on less than 4" of ice by yourself unless you weigh 150 lbs or less. Never fish within 15' of anyone on 4" of ice that weighs, +- 20lbs of the 250 mark. And all the more so if you can't do the 40 in less than 10 seconds on ice.
Remember the 1st principle key to actually helping someone is to NOT become a victim yourself. Make sure you do not get wet when fetching others out. That means have at least 100' of strong rope tied to a tree so you can't be pulled in by bigger buds. If you fish Hopatcong make it 1000' of rope or just call 911 and go back to jigging. You did your good deed for the day.
For those whom you don't like bring a bag of balloons and throw the bag to them with instructions on how to blow up balloons and float while hypothermia is setting in. For special effects you can play Zeppelins version of "In My Time of Dying". You will soon find out if they believe that "God" exists and you'll hear them renounce all the blasphemous comments they made about how god is a man made concept for only weak minded persons.
Never fish ice that is over moving water, like a river. The risks are to great and risking your life to catch fish is very foolish (another reason why I like boats better, especially in winter on a river). In fact, you really don't just risk your own life but others lives as well. Namely, any rescuers that have to come to your foolish aid.
Review and inventory all equipment and safety procedures ahead of time (like right now) and periodically review them during the season to keep them fresh in your mind.
