We are new RVers and I have some concern over safety in RV parks where there are vehicles moving with pedestrians walking. We have almost been hit a couple of times while walking due to the quietness of bikes, golf carts and autos. Please make a noise like beep-beep, or blow your horn with a little toot. I think all bikes should have a bell on them, at least. We have met great people, but their driving habits are questionable. Thanks.
