Let me give you a first hand perspective. I live on a cul-de-sac in Glen Rock and my wife and I feel there are definitely positives and negatives. The positives outweigh the negatives by a long shot. Positives: we can let our kids play outside and not have to constantly worry about traffic, the cul-de-sac is an additional place for them to play (my son and the kids on our block ride go-karts and play four square all the time), the cul-de-sac creates great family interactions - all of the parents are outside watching their kids and hanging out - the people who are at the end of the street (not the circular portion) are not nearly as involved as those who are actually in the cul-de-sac portion of the block, most importantly (for a new homeowner) - it really forces you to have interaction with your neighbors - which is a good thing (most of the time), and as many have said - other parents like the safety of a cul-de-sac, so they would be more inclined to allow their children to hang out at your house, rather than a house on a busy street. Negatives: I have to say that my son tends to hang out with kids that are not his age (most are younger) because they are always outside in this isolated area of the cul-de-sac, if you don't like some of the kids in the cul-de-sac, you will have an awfully hard time trying to discourage your kids from playing with them, and if you have neighbors who you don't get along with, you can never really escape them because the cul-de-sac actually acts as a inescapable social vacuum (which has pluses and negatives). Lastly, I agree with Marc below - try and get a kid inventory - it should be easy considering the kids will be outside during the day on the weekend due to the nice weather. Good luck.
