I'm new here, looking for some advice. I have two kids who will be going into kindergarten and first grade this year. Their school is close enough to walk, but due to their different schedules, I would have to walk to and from school three times a day (it'd take me over three hours total every day) We're so close I also feel it'd be silly/wasteful to drive them (not to mention the horror of the endless line of parents in cars). Biking seems like the perfect option but I'm not sure where to start. My youngest would need to be "on" my bike in some way, she's too young/inexperienced to be on her own. Can anyone tell me how the trail-a-bike sort of things have worked for them? Would it be difficult to use on hills? We live in a very hilly area (there'd basically be *no* flat ground there or back). Is there a bike for me that would work best with the trail-a-bike and hilly terrain? Thanks in advance, I'm really excited to figure this out and get us on some bikes!
