Big one yesterday, picked up 5 tiles near Shaftesbury:
Conveniently part of a ride from my new place to my parents' house, so a little over 40 miles (the most direct route is 25 and involves the unpleasant A350, so I went a mile along the trunk A31, then did the A350, but the calmer 30-40 limited section).
That took me from multiple 19x19 squares to a 23x23,
and were the last tiles in that region of Dorset. Now my attention has to turn to the West. Although I'm literally living two miles away from 3 unclaimed tiles... those are Brownsea island.
