We are traveling by car and trailer (some hotels) this year and are looking at destinations for late Summer and Fall. We might be in upper Minnesota and heard that the Fall colors are quite impressive in Duluth. Is September too early to visit? Our visit can only be for a short time, maybe a few days. Also, are there other events happening during Sept. or possibly early Oct. in the Duluth area? In case of rain/snow (?) what entertainment options would we have. Maybe we would be better off staying more south but we hear so much about going "up North".
Links to Websites or publications would also be appreciated.
