I have been asked by a newcomer to the sport what is a safe riding plan for taking a 6 year old passenger with as a passenger. In other words how long between stops, time and distance. I have been riding for decades along with my kids and grandkids, but I haven't been able to come up with definitive guidelines, common sense is not an answer when the person has no experience. This is kind of like someone going to Florida for the first time and asking how long is it safe to be in the sun. There must be some guidelines taking into account the temperature, wind chill, etc. Can anyone help me out here?
