Guard rails are a safe and secure place to hide geocachers. This is a multi-cache where every stage is hidden in a GR (Guard Rail) and is designed to do on foot for most if not all of the stages don't have places to park a car.
This multi only has a bit of walking so not as annoying as the other ones. A good place to start perhaps.
In all stages the coords point to a GR. A flat, taped ,magnitzed cache has been hidden in a GR with the coords to the next stage. If otherwise indicated, all hides are in the end of a GR. If there are several GRs in the area, you'll have to check all of them.
Good luck! I hope you enjoy and I hope you don't get too annoyed.
