I don't know that there have been that many threads exclusively dedicated to paying for SAR. However, I do recall a number of times when threads drifted into that topic. I know I personally had a number of spirited exchanges with Benjammin about paying for SAR. (We haven't seen much of Ben lately?) Indeed, the topic came up this time as part of a lost hiker found thread, not as a stand alone topic.

Regarding revisiting old topics, I'm of two minds about it. Some topics (bear spray vs guns) really have been beaten to death. Absent some really new compelling hard data (not just another isolated anecdote or opinion), I don't see much value, and I don't choose to participate much. But hey, ETS is an open forum, and if others wish to flog that horse, have at It.
