last week at a local lake 4 different rescue squads from 4 different towns (essential personnel) had to get recertified for water rescue methods and tooling. i wrapped myself up donned appropriate safety gear (multi mask. helmet, and life jacket) kept my distance and clicked away. here is a sample of the effort these people put into their voluntary service to be ready when things go sideways. the ice that day was approx 6" thick. the holes were cut using a chainsaw.
