We have found him!!!! It was our faul that the Bug get missing. Hexenberg was our first Cache we found and because of that reason we had no idea what a Travel Bug could be. In addition to that, our child took almost everything that was in the little box out and we don´t knew that. So last week we found him at home.
I hope that you do not have to be angry at us. Today we have put the Bug in an other Cache called "Fehrmanns Mühle"
