I'll admit it, I love to play tourist. Over the years, I've come to know several regions very well. On a recent trip to San Francisco, CA, I recently came up with a concept for a multi-virtual cache.
My thought was that I could have a set of coordinate for landmarks (that tourists would naturally visit on their travels). Each landmark would include a question about the location for verification. With enough research, this could even become a GPS tourist guide.
Another concept I thought of would be a cruise. Cruise ships travel the same routes week after week, visiting the same places. When I take a cruise, I could find a landmark at each stop, develop a question around it (for verification), and acquire the coordinates. Then Cachers that go on that cruise would have help in deciding what to see, but could also play the game as they tour the globe.
Are these valid caches? If so, do I mark it as a virtual, or a multi? Does anybody see any potential problems that might pop up?
