First, thanks to all who responded to my other Black Forest post!
I have found nice info on Freiburg and am starting to wonder if I should skip Heidelburg and spend time in Freiburg and maybe another town along this train route instead.
When we went to Italy, our fondest memories are often of the smaller towns that most never heard of.
Thoughts, opinions, and recommendations on Mannheim, Karlsruhe, Offenburg, & Freiburg anyone?
Note- due to wide-varying ages of our group, we are looking to stay on the major train routes.
