THING 32. GOOGLE MAPS AND MASHUPS

I created a map called "Walking and eating in the Roseville area" (exciting title, huh?). I outlined Bennett Lake in Central Park, Lake Como and Snail Lake. I clicked on places of interest and then under dining checked Seafood, Italian and other. This adds dots to the map to show the location of the restaurants. So far so good. How do I take some of the restaurants off the map and leave others? I can't find a way to do this. Also I discovered that the restaurant dots disappear when you sign out and then sign back in.


Google Maps: 100+ Best Tools and Mashups has many interesting maps. I looked at these two:

Prescription drugs in drinking water across the United States-- The only drug that showed up for Minneapolis was caffeine.

If the earth were a sandwich-- This is the point on the earth that is the exact opposite of the selected point. I selected Minneapolis. It's opposite was somewhere in the Indian Ocean between Madagascar and western Australia.
