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!
No luck on the first go, and found after a short struggle on the walk back. It broke it up, so there's that.
Don't miss the Winter Geolympix. We've some cool stuff coming!
