The basic version is free...and it's all a casual user is likely to need. I just download it and work from there... it does require some bandwidth and speed to work well. It doesn't seem to have any bad habits, except taking up LOTS of computer memory if you try to save too many settings.

I don't think Blind River has been done in fine detail yet, though. San Diego is totally documented. They have gone down the major streets around my area, but not down my street. I can look down on it from maybe 2000 ft up, but not street level.
