If you have children that in strollers then you probably have something like the bob revolution duallie. I have a double stroller and it is nice because the kids are side by side. I personally do not like the ones that have the kids one in front of the other becasue the kid in the back is stuck looking at the other kids head and they don’t have that much of a veiw of things around them. This way they are side by side…it really does work out so nice.
