How many angels can dance on the head of a pin?

One can argue that being able to nibble at the edges or take a long hike to reach the entire length of that section of the river constitutes having access. And while that may be technically accurate I would suggest that it is not the same level of access that the property owner is selling to a select few at a high price.

But the point that increasing demand without a plan to ensure ongoing access has reached a crisis point is spot on. Private property owners have tired of the problems or have sold out to higher valued use of the properties which are incompatible with continued public access.
