excuse the newb question, what qualifies for further research when looking at a memory map picture
so far from what I can work out its
+ + + + + + + + = plus symbols indicate BOAT
...... = large fullstops either red or blue indicate right of way likely to be old RUPP but potentially still legal
diamond .... diamond ... diamond = diamonds with fullstops inbetween unconfirmed classification but right of way
any comments on the above?
