I was reading the really good thread on looking to buy a house on a street where kids play outside with each other and how that might be important for parents of only kids, which we probably are.

It's too early for me to worry just YET but ... how do you ensure that your only child has enough to do/friends to play with? Does it always have to be very structured? We won't be living in an area with a neighborhood school situation when DS will be old enough for friends ...

Thanks for any tips and for your stories!
