That's the truth, you have to be exact on what you want or you'll get something close. Great maps, but no more detail than you can get in Google earth.
I bought The National Geographic mapping software years ago and have used it since to build my own maps. Hooks right up with my gps and even allows pictures to be placed at way points. Things been a gold mine. The company is a bit of a tree hugger, but those huggers love to geocache. They upload info of public places you can use when scouting out.
