Rick, from what I gather from people who have done the caches, they are all hidden the same way, on the same side of the road. That nearly eliminates the hunt time. The series is designed so people can find a lot in a short time. Many are using non-standard ways of logging them, like replacing the film can with another which has been previously logged. Some caches of this type people have stuck stickers on the outside of the film can instead of signing the log. Who knows, some may figure if they stop at each location it is good enough, it's not like the owner verifies the logs. Also, they are considering one day 24 hours. These are not found in a manner in which we are used to. Doing it alone has to be considerable harder, but I imagine it can be done by someone determined enough.
