Simply Paul: 13 miles on foot? There's a reason this series has suffered a lack of maintenance since my bicycle was stolen... So, time to let it go. Sincere thanks to everyone who did this cache and/or the series, and to Sustrans for the permission to place them. Sorry for any DNFs here!
I found the replacement box (thanks again) ok, and the insulator from which this cache takes its name, but no sign of the original/lost box. I'd also forgotten how steep that ramp is!
Don't miss the Winter Geolympix. We've some cool stuff coming!
