As a NAFFrunner trotting around the backroads I have eyed off the old and new bridges as likely hides. They seem both obvious and interesting and mostly include a safe pull out area, they tend to prompt time for reflection and appreciation of times past and road construction challenges. I lean towards easy, safe (child friendly) hides which encourage a detour from the usual route. I also support cache in trash out and urge you to enjoy the freedom and luxury of this often crazy and addicive pastime we call Geocaching. They are out there – over to you.
