Hi Jherome, How is the map visualization coming along? Regarding your latest ticket about upgraded/downgraded routes (like Tagaytay-Nasugbu) I think we need to fix the classification scheme first before tinkering with actual map fixes (or even map reversions).
~Eugene P.S. I think it's okay to have Tagaytay-Nasugbu as trunk because it provides a loop with Ternate/Maragondon and Aguinaldo Highway and Governors Drive in an increasingly urbanizing area.
