We should keep in mind that folks are skating in fairly early season conditions this year. From what is being shared, these skaters are prepared for the risks. As the winter progresses and ice builds on our lakes, the risks of a plur (or swim) will drop, but are never zero.
So why skate now? For one thing, its been many months since we last skated and many of us are eager to get out on the ice. For another, some of the best ice presents itself when it is relatively newly formed, before snow and wind have had the opportunity to mar the perfect black surface.
Skating on thinner ice presents risks, no doubt. There is a case to be made that the preparations an experienced skater makes to venture forth onto thinner ice may make for a safer overall experience than a trip on established, thicker ice, when our guard is down and we may chose to skate with fewer precautions. The safest skaters always skate expecting a swim. Some, and I'll include myself in this category, will skate alone or without a drysuit on ice that I know is mature and thick (>6") on a cold day. However, accidents happen on thick ice too.
The emails that have gone out recently, to me, show a really healthy appreciation for the risks involved and the value of sharing experiences on the ice. We all learn from them. I consciously did not say 'mistakes' on the ice, because if you choose to skate on 2" or less of newer ice, falling through is not really a mistake, its a real possibility that must be prepared for. Some skaters will choose not to skate on ice less than 3-4" thick. I see that as a very reasonable choice. Others want to get time on thinner ice, and if proper precautions are taken, I do not find that unreasonable either.
Some skiers ski the back country woods, others stick to patrolled trails, no problem with either approach if the skier is prepared for the adventure they choose.
