The Dartmoor Forest series is an excellent series of caches, but few could achieve it on one walk, even taking 2 or 3 days. There are 54 caches in total and I was FTF on 16 of them including the bonus, but I did a total of 19 walks on 14 different days, my longest walk being 15 miles. In total I probably walked 80 to 100 miles, but unfortunately lost all my GPS tracks. The series was placed over a year ago but has still only been completed by 5 cachers! Probably not what dartymoor had in mind when he started this topic!
