From Hardy Huber, inventor of the TravelScoot:
This trailer picture was taken with former Munich Mayor (for the last 20 years). He is very popular in southern Germany and approached me last Sunday when he spotted me riding along with a walking impaired friend. He is interested to get scooter and trailer for his walking impaired wife, who otherwise he would need to push her in a wheelchair.
He recognized immediately that this would be much more fun for both of them whenever she needs to be moved over a distance.
