The restrictions being considered for Phoenix area hiking due to the heat are wrong. Every single person has a different ability and different limitations. Whether to hike in any conditions, heat, rain, thunderstorms, cold, etc., should be an individual decision, not government.
There are obviously people who have health conditions that would make it inadvisable to hike at any time. Therefore, the next thing we should expect from our government nannies will be a requirement for a doctor’s authorization for anyone to hike.
A much better change would be a “user pay” approach, that is, charge people for rescues. The word will get around quickly and hotel concierges will start advising their health challenged guests to consider the conditions.
