Hi, Well anyone who wishes can reverse the changeset where I moved the boundary. It bothers me not :-)
Am I the only one who can see the similarity between the shape of the border and the shape of the river ? Still unless we get a good source of municipal boundaries, I'm finished with boundaries now. Back to error fixing and tracing images. Oh, maybe I'll check the boundaries in Manila that I haven't checked yet, but I need a break from boundaries for a while.
