Sorry for the late feedback but our customer didn't answer earlier... They like the #28 most - but ask for an integration of their old road-sign - which you find here: https://dl.dropboxusercontent.com/u/3520444/Schild.jpg
Could you combine those two (I don't know how...) ... maybe instead of the
"ammer amper radweg"
in your logo you could paste the letters AAR and underneath the logo you could insert "Ammer-Amper-Radweg" but both in their font?
sorry the last comment was not 100% right, I like the two colors of blue - you can keep that. But: I'm not comfortable with the first line above AAR even its the only symbol for water/ river. May there be another space for a river symbol? Its difficult.
Please post one logo with like #42 with the new green in the mountains and another logo with the new green AND more of the river.
