Strange things are happening here too, of late-- repeats of earlier msgs., replies before originals; and some of mine take up to 24 hours to get back to me. Plus a couple bounce-o-grams for msgs I hadn't sent. I'd been blaming for all but the last......... ---------------------------------------------

It is neat, and I don't want to rain on the parade, or pontificate...but there's a couple problems IMO. 1. a map with such a detailed coastline would have to be extremely small-scale, no? Seems to me it also implies a rocky land mass because otherwise--- 2. erosion by the surf/tides would surely tend to smooth out a lot of irregularities. (I'm thinking of the east coast of Florida, which even on small scale maps tends to be a gentle long curve, with occasional inlets) 3. a riverbank, lakeshore, or island in an uninhabited area, might be quite irregular; but would tend to get smoothed out within a town or city, where the hand of man has set foot. When I was playing around with my (fairly large scale) hand-drawn maps in PAINT, I could blow up the bmp and make things as irregular as I wanted, but when reduced back to normal size, most of it didn't show up.

(snip Mike's suggestion, which might be worth a try.)
