I prefer parking coords to avoid complications. I don't mind exploring and learning about the area. What I don't like is assuming I have the right spot...only to learn on the way out that it's private property. In most cases....having the full listing helps to prevent much of it. You can't assume that everyone will have a printout...or an expensive GPS w/descriptions.
I'm a bean spiller! Ask me for a hint and I'll tell you right where it is. Especially if my intention was to get you to a specific spot. If my intention was to trick you with a well hidden cache, I am more frugal with my hints.
