UKGeocachingHour (#UKCacheHour) on Twitter, every Tuesday, 8-9pm
Having said that, I don't know if it'd be a good idea to register just in case before I cover these more obscure D/T types
Ropes and torches are needed to find the actual cache when you are finished I know some here would see that as a further incentive to complete the challenge
Registered my intent. Once my exams are over in May, I may (or may not) have a good crack at completing the challenge.
