I would suggest plenty of access from the trail to public streets. That seems to be a huge problem with some of these type of trails. Its almost like they force users to go across private property to get on or off the trail because it is so hard to do so otherwise. This situation is not real helpful with the property owners along the trail.

Personally, I prefer hiking in the forest and consider paved trails to be an abomination of sorts.

But these kind of trails are mostly for the guys on bikes. And they prefer paving to dirt.
