Our house is at the end of a cul-de-sac with a long, sloped driveway. The neighbor kids seem to love it for riding their scooters and tricycles down....but it makes me uncomfortable! I do not know my neighbors well, and don't know their kids (young ones, ages 3-7) at all, and I just find it weird that they traipse all over my driveway and sometimes my lawn. DH says I'm being silly, and I am glad that they are outside playing instead of inside lazing about, but I don't know, it irks me

So, tell me, what do YOU think is acceptable? I haven't said anything to the kids or parents because I'm probably being silly (and because I hate conflict :p), but I do worry about safety/liability.
