It must be taking you on a wild goose chase, cause from where I life (London) to Salt Springs Fl is only about 1300 miles Straight up I75 to Detroit and then 120 east to London.

Muskoka is a nice area to ride in, lots of roads to choose from. If you can avoid the weekends, this is the heart of cottage country and from June to September everybody and his brother from the Toronto area will be up there for the weekend.
The good news is there are plenty of nice places to eat drink and sleep!
