Little idea… I noticed the blimp flying about in the harbour today. Guessing its on some kind of track it follows around the bay.
I thought it could be really fun to let people power the blimp by riding it. I think it would be a great idea for that to be a group time trial/race activity - i.e., how fast can your team race the blimp round a course. Possibly even let someone drive with their phone companion app!
