There are 27 caches in 6.5 miles or one every 420 yards on average, so approximately at quarter mile intervals. They are closer together than I would like, but these were placed specifically for those who were looking for some sort of Dartmoor Power Trail. It will be interesting to see how many bother with them, but it has already attracted considerable interest including cachers we rarely see on Dartmoor.
As regards 3 and 23, they are on opposite sides of the river and are spaced accordingly. They are not supposed to be done consecutively.
