We've started leaving the car home more often and have two little ones (1 and 3). If anyone is interested, my website is: www.tinyhelmetsbigbikes.com. We've done the trailer thing (great!) and have now upgraded to a Yuba Mundo (www.yubaride.com). I love how it gets my kiddos up off the ground and within arms reach. The boys love riding! I just try to be as visible as possible and use common sense.
